Authorities are investigating a suspicious package that may have been sent to Joe Biden but was misaddressed, according to numerous reports.

CNN reported that the package is considered suspicious because it is similar to the bombs sent to various addresses across the country on Wednesday.

An analyst on MSNBC said that investigators believe the wrong address may have been written on the package and it could have been sent back - perhaps to the office of Debbie Wasserman Schultz.

Postal service workers have been made aware of the package possibly being in the mail system, Jonathan Dienst told MSNBC's Chris Hayes on Wednesday.

A beefed up security presence was seen outside the former vice president's home in Greenville, Delaware on Wednesday.

Investigators conducted a sweep of the premises and did not find anything suspicious, according to the Delaware News Journal.

The search was conducted by New Castle County Police.

There was no police activity in and around the home on Wednesday, authorities said.

The seventh threat was announced as federal authorities investigated a second suspicious package sent to Democratic Rep. Maxine Waters.

Officials flagged a piece of mail that was sent through a LA sorting office.

It forced the evacuation of a mall outside LA. </s> A second suspicious package addressed to former Vice President Joe Biden reportedly turned up at a Wilmington, Delaware, postal facility Thursday morning.

The package is similar to others containing pipe bombs that were sent to high-profile figures including former Secretary of State Hillary Clinton, a source told The Associated Press.

Postal supervisor Sherina Dawson told 6abc Action News that an employee called attention of the package because it had Democratic California Rep. Debbie Wasserman Schultz as the name on the return address. Dawson said the item inside the package was similar in shape to a flashlight.

Police shut down the area around the postal facility, reported 6 ABC.

Police also shut down a postal facility in New Castle, Delaware, around 6 a.m. Thursday morning after the first suspicious package addressed to Biden was located. The FBI has taken over the investigation of the facility, reported 6 ABC.

“This country has to come together. This division, this hatred, this ugliness has to end,” Biden tweeted Wednesday before any suspicious packages addressed to him were located by law enforcement.

Law enforcement got a tip about a mysterious package addressed to the former VP and arrived at his Delaware home Wednesday night before the first package was located.

Biden is the latest intended recipient of the mystery bombs. Other intended recipients of the explosives include:

President Donald Trump addressed the bomb scares at a rally in Wisconsin Wednesday evening. (RELATED: Los Angeles Postal Facility Evacuated After Finding Second ‘Suspicious’ Package Addressed To Maxine Waters)

“Any acts or threats of political violence are an attack on our democracy itself,” President Donald Trump said at a rally in Wisconsin Wednesday evening. “No nation can succeed that tolerates violence or the threat of violence as a method of political intimidation, coercion or control. We all know that. Such conduct must be fiercely opposed and firmly prosecuted. We want all sides to come together in peace and harmony. We can do it.”

CNN's Jim Sciutto cited two law enforcement officials with the development Wednesday evening.

NBC News contributing correspondent Jonathan Dienst said on MSNBC that law enforcement officials are concerned that a potential package addressed to Biden was sent to the wrong address and therefore shipped to an office of Rep. Debbie Wasserman Schultz in Florida because that address appeared on the return label. He added that information from that U.S. Postal Service indicated that the package is out somewhere.

An array of Trump critics around the country were sent potentially explosive devices this week, including former President Barack Obama, former Secretary of State Hillary Clinton, former Attorney General Eric Holder, California Rep. Maxine Waters, and liberal billionaire philanthropist George Soros. Another package was sent to ex-CIA Director John Brennan at CNN's offices in New York City.

The potentially explosive devices included in these packages, sent in manila envelopes with a return address to Wasserman Schultz's office, are being examined by the FBI.

Earlier in the day it was reported that the package addressed to Holder was sent to the wrong address and therefore sent to Wasserman Schultz's office.

Authorities have yet to say they have a suspect.

"This country has to come together. This division, this hatred, this ugliness has to end," Biden tweeted earlier in the day. </s> As the FBI confirmed an 11th suspicious package had been recovered in Florida, the New York Police Department is investigating a 12th package Friday.

The package in New York found at a mail processing center in Manhattan was addressed to CNN in the care of former intelligence director James Clapper. Clapper is a contributor at CNN.

Clapper also testified at a Senate Judiciary subcommittee hearing on Russian interference in the 2016 presidential election in May of 2017.

The FBI confirmed an 11th package has been recovered in Florida. It is similar in appearance to other suspicious packages sent to democratic leaders. This one was addressed to New Jersey Senator Cory Booker.

Several of the packages went through a U.S. Postal facility in Opa-locka, Florida, two law enforcement officials familiar with the investigation said.

The Miami-Dade Police Department tweeted that its bomb squad and K-9 Unit are providing assistance to federal partners at the USPS Opa-locka mail facility.

"This assistance is as a precautionary measure," it said. "We cannot provide additional information at this time due to the active nature of this federal investigation."

A series of pipe bombs and suspicious packages intercepted this week left the nation stunned and authorities hunting for a serial bomber who is targeting prominent Democratic figures and CNN.

Authorities intercepted all packages before they were delivered to their intended targets. None of the bombs detonated, and no one was injured.

Here's a breakdown of everything we've learned all week:

How many packages have been sent so far?

 Authorities have intercepted at least 10 packages.

They were sent to:

 Billionaire investor George Soros: One package, sent to his home in New York.

Bill and Hillary Clinton: One package mailed to their home in New York but intercepted by the Secret Service.

Barack Obama: One package mailed to Washington, D.C., but intercepted by the Secret Service.

Former Attorney General Eric Holder: One package addressed to him but sent to the Florida office of Democratic lawmaker Debbie Wasserman Schultz.

Democratic U.S. Rep. Maxine Waters: Two suspicious packages: one intercepted at a congressional mail-screening facility in Maryland and a second one found at a postal facility in Los Angeles.

John Brennan: A "live explosive device" was addressed to the former CIA director and delivered by courier to CNN's offices at the Time Warner Center in New York.

Former Vice President Joe Biden: Two packages found at post offices in Delaware.

Actor Robert De Niro: A suspicious package sent to him at the Manhattan building where his production company is based shows similarities to the other pipe bomb packages.

Did the packages have any similarities?

The devices sent to Soros, Brennan and the top Democratic officials appeared to be pipe bombs, said Bryan Paarmann, FBI special agent in charge of the counterterrorism division in New York.

An initial examination shows they are rudimentary but functional, and have similar construction. At least one contained projectiles, including shards of glass, a law enforcement official told CNN.

The packages were in manila envelopes with bubble-wrap interior, the FBI said, and each package had six American flag Forever stamps on the envelope. The devices had suspicious-looking packaging, and at least one had a timer that can be bought for a few dollars online and should be easily detected when mailed or delivered.

Were the pipe bombs designed to go off?

In a news release, the FBI called them "potentially destructive devices." The presence of what was believed to be pyrotechnic powder caused investigators to believe they could detonate, but it appeared the packages were handled and moved through the postal system without an explosion.

Based on X-ray image of one of the devices, there appeared to be hazardous materials present, Anthony May, a retired ATF explosives investigator, told CNN's Brooke Baldwin.

But it also appeared to be missing a crucial component for a functioning explosive device.

Law enforcement officials told The Associated Press that the devices, containing timers and batteries, were not rigged like booby-trapped package bombs that would explode upon opening. But they were uncertain whether the devices were poorly designed or never intended to cause physical harm.

Where are the packages now?

The devices sent to Clinton, De Niro, Obama, the CNN offices and Waters' East Coast office are either with the FBI or headed to the agency's lab in Quantico, Virginia. A controlled detonation was conducted for the device sent to Soros, while the one mailed to Waters' West Coast office was rendered safe by a bomb squad.

It's unclear where the others are.

A suspicious white powder found in an envelope along with the device sent to Brennan and CNN was tested and found not to be anthrax or other known agents, a source said. Additional tests will be done in the coming days. </s> WASHINGTON/NEW YORK (Reuters) - Federal agents searched a U.S. mail facility near Miami on Thursday night in the race to find who sent 10 pipe bombs to prominent Democrats and critics of U.S. President Donald Trump as leads pointed to Florida as the packages' possible origin.

Investigators treated the devices as "live" explosives, not a hoax, said James O'Neill, the police commissioner of New York City, where two of the packages have turned up since Wednesday.

A federal law enforcement source told Reuters the devices were thought to have been fashioned from bomb-making designs widely available on the internet.

Investigators believe the packages, which were intercepted before reaching their intended recipients, went through the U.S. Postal Service at some point, that source said. None detonated and no one has been hurt.

Homeland Security Secretary Kirstjen Nielsen, in an interview with Fox News Channel, confirmed that at least some of the packages were mailed in Florida.

"Some of the packages went through the mail. They originated, some of them, from Florida," she said. "I am confident that this person or people will be brought to justice."

A bomb squad examined a mail distribution center near Miami where authorities believe several of the packages were processed, Miami police said.

Miami-Dade County Police said their bomb squad and its canine unit were on the scene in Opa-locka, Florida, as a precautionary measure, working alongside federal authorities.

Authorities have branded the parcel bombs, coming less than two weeks before national elections, as an act of terrorism, though they have declined to say how functional the devices were.

A number of bomb experts and security analysts said that based on the rudimentary construction of the bombs it appeared they were more likely designed to sow fear than to kill.

The first package surfaced on Monday at the Westchester County, New York, home of billionaire financier George Soros, a leading donor to the Democratic Party and various liberal causes.

On Wednesday, the FBI identified five more targets - President Barack Obama, former Secretary of State Hillary Clinton, former Attorney General Eric Holder, former CIA director John Brennan, and California Representative Maxine Waters. Two packages were found addressed to her.

Brennan's package was sent in care of the Manhattan bureau of CNN, where he has appeared as an on-air analyst.

On Thursday, the investigation widened with the discovery of three additional packages - two intended for former Vice President Joe Biden in his home state of Delaware and one for Hollywood actor Robert De Niro in Manhattan.

"It does remain possible that further packages have been or could be mailed," William Sweeney, assistant director of the Federal Bureau of Investigation, told an afternoon news conference in New York.

The FBI has said at least five of the packages bore a return address for the Florida office of U.S. Representative Debbie Wasserman Schultz, who formerly chaired the Democratic National Committee. Holder's package ended up rerouted and delivered to the Wasserman Schultz return address.

Sweeney said the manhunt for perpetrators involved hundreds of investigators nationwide.

The bombs have heightened what already was a contentious campaign season ahead of the Nov. 6 elections in which Trump's Republican Party will try to maintain majorities in the Senate and House of Representatives. Democrats have seized on the episode as a symptom of the harsh rhetoric Trump wields against his rivals.

Trump condemned the bombs but later blamed the media, his frequent foil, for much of the angry tone in the nation's political discourse.

No one has claimed responsibility, and the public was asked to report any tips. The parcels each consisted of a manila envelope with a bubble-wrap interior containing "potentially destructive devices," the FBI said. Each bore a computer-printed address label and six "forever" postage stamps, the agency said.

Some of the packages sent to New York locations had envelopes of white powder in them, but Sweeney's examination had shown the substance posed no biological threat.

Sweeney said all of the devices were being sent to the FBI's crime lab in Quantico, Virginia, for analysis.

Most of the intended recipients were high-profile Democrats and all were known to be outspoken critics of Trump, foils for his political rhetoric or both. Trump long questioned Obama's U.S. citizenship and referred to Clinton, whom he defeated in the 2016 presidential race, as "crooked Hillary." He has derided Waters publicly as "low-IQ Maxine." The president revoked Brennan's security clearance after the ex-CIA chief, a veteran intelligence official in Democratic and Republican administrations, lambasted Trump's Russia summit performance as "nothing short of treasonous." Biden once said he would have fought Trump if they were in high school, while De Niro received a loud ovation when he hurled an obscenity at Trump at the Tony Awards in June. At a Wisconsin rally on Wednesday night Trump, who has denounced news media organizations as an "enemy of the people," called attention to "how nice I’m behaving tonight” but on Thursday morning he attacked the media again. "A very big part of the Anger we see today in our society is caused by the purposely false and inaccurate reporting of the Mainstream Media that I refer to as Fake News," Trump wrote. "It has gotten so bad and hateful that it is beyond description. Mainstream Media must clean up its act, FAST!" </s> Federal authorities arrested a man in Florida on Friday in connection with the mail-bomb scare that widened to 12 suspicious packages, the Justice Department said.He has been identified as Cesar Sayoc, 56, of Aventura, Florida, according to law enforcement officials.Law enforcement officers were seen on television examining a white van, its windows covered with an assortment of stickers, in the city of Plantation.

WASHINGTON — A suspicious package addressed to Democratic Sen. Cory Booker of New Jersey, and similar to crude pipe bombs sent to prominent critics of President Donald Trump, was recovered Friday in Florida, the FBI said.

Another addressed to Former Director of National Intelligence James Clapper also has been discovered.

None of the devices have exploded. The FBI is doing a nationwide manhunt for whoever is sending the pipe bomb packages, and officials are trying to determine if the sender or senders was trying to sow fear or actually cause physical destruction.

Early Friday, the FBI tweeted that it “has confirmed an 11th package has been recovered in Florida, similar in appearance to the others, addressed to Sen. Cory Booker.”

Booker is a potential 2020 presidential contender. Devices have also been sent to former President Barack Obama, former Vice President Joe Biden, Hillary Clinton and CNN.

Clapper said he is not surprised he has been targeted with a suspicious package.

Clapper told CNN Friday morning that the devices sent to prominent critics of President Donald Trump in recent days were “definitely domestic terrorism.”

Two officials told the AP that a package was discovered at a postal facility in Midtown Manhattan. One official said it was addressed to Clapper. The officials weren’t authorized to discuss the investigation and spoke on condition of anonymity.

Clapper described the situation as “serious,” but said it is “not going to silence the administration’s critics.”

Clapper stressed that he did not want to suggest any direct link between Trump’s past rhetoric and the packages. But he said Trump should bear responsibility for the “coarseness and uncivility of the dialogue in this country.”

At a press conference Thursday, officials in New York would not discuss possible motives or details on how the packages found their way into the U.S. postal system. Nor would they say why none of the packages had detonated, but they stressed they were still treating them as “live devices.”

“As far as a hoax device, we’re not treating it that way,” police Commissioner James O’Neill said.

Details suggested a pattern — that the items were packaged in manila envelopes, addressed to prominent Trump critics and carried U.S. postage stamps. The devices were being examined by technicians at the FBI’s forensic lab in Quantico, Virginia.

The packages stoked nationwide tensions and fears as voters prepared to vote Nov. 6 to determine partisan control of Congress — a campaign both major political parties have described in near-apocalyptic terms. Even with the sender still unknown, politicians from both parties used the threats to decry a toxic political climate and lay blame.

“A very big part of the Anger we see today in our society is caused by the purposely false and inaccurate reporting of the Mainstream Media that I refer to as Fake News,” Trump said on Twitter. “It has gotten so bad and hateful that it is beyond description.

Explosive devices targeting U.S. Senator Kamala Harris and billionaire Democratic activist Tom Steyer were intercepted Friday in what authorities called a Florida man’s plot to mail more than a dozen pipe bombs to politicians and public figures critical of President Trump.

An improvised explosive device, or IED, sent in a package addressed to Harris was discovered by a post office worker in Sacramento, according to the FBI. A second bomb in a package addressed to Steyer was found at a mail processing facility at 1625 Rollins Rd. in Burlingame.

The packages were discovered on the same day a nationwide manhunt ended with the arrest of Cesar Sayoc, 56, who was taken into custody in Plantation, Fla. His fingerprints and DNA were allegedly found on another bomb mailed to Rep. Maxine Waters, D-Los Angeles.

At least 13 packages containing pipe bombs were sent to Democratic Party leaders including former President Barack Obama, former Vice President Joe Biden and Trump’s 2016 election opponent, Hillary Clinton, authorities said.

Postal service workers in Burlingame were escorted out of the Rollins Road facility after the device was discovered. Agents continued investigating the scene Friday afternoon.

The device was taken off-site, according to Burlingame police. FBI officials in San Francisco tweeted that the package was “rendered safe” around 1 p.m.

Mail carrier Cynthia Maffei said she was about to leave the facility around 10 a.m. when the package sent to Steyer was found by another employee. Thirty minutes later, Maffei said, the post office was evacuated.

“They were seriously telling us to get out now,” she said. “It makes me nervous.”

Supervisors told her to “forget everything,” get out of the building and not come back for the day, Maffei said.

Steyer ran the hedge fund Farallon Capital for 26 years and has donated $65 million to Democratic candidates and environmental causes during the 2016 elections, according to Forbes. He has also led an effort to have Trump impeached.

At a youth summit Friday, Trump said he was “pleased” with the arrest of Sayoc, but many Democratic leaders blamed the president’s rhetoric for creating a dangerous political climate.

Lily Adams, a spokeswoman in Harris’ office, said it was time for “leaders across the political spectrum to take seriously the power they hold,” adding that elected officials should “elevate our discourse and bring people together.”

Steyer tweeted out a statement calling on the Republican Party to denounce any attacks “on the rights and dignity of any American.”

“We are seeing a systematic attack on our democracy and our rule of law that extends much further than just one isolated terrorist in Florida,” Steyer wrote. “Whether it’s voter suppression, voter intimidation, attacks on our free press, gerrymandering, or attempted violence — the trust and norms that are the actual basis of our civil society and political system are being eroded.”

In total, 13 IEDs consisting of six inches of PVC pipe, a small clock, battery, wiring and energetic material have been found, according to the criminal complaint against Sayoc. FBI Director Christopher Wray warned that more packages could be found in the coming days.

Authorities declined to comment on the motive behind the bombs, though Sayoc, who has a long arrest record, had expressed contempt for liberals and reverence for Trump, including on social media. In Florida, authorities seized Sayoc’s white van, which was adorned with pictures of Trump and stickers critical of Democratic leaders and news network CNN, another of the alleged bomber’s targets.

Rep. Jackie Speier, D-Hillsborough, told The Chronicle that Sayoc’s targets are people on “the president’s enemies list.”

Trump “has gone out of his way to throw verbal bombs,” Speier said. “He elevates people who do violent things. This could have been catastrophic to our country.”

Attorney General Jeff Sessions said he “didn’t know” why Democrats were targeted.

Sayoc was charged with five federal crimes that included transporting explosives across state lines, illegally mailing explosives, threatening former presidents and other people, threatening interstate communications, and assaulting assaulting federal officers, according to the criminal complaint.

He could face up to 48 years in prison if convicted, Sessions said.

Prior to the announcement of the arrest, Trump was criticized for bashing CNN in a Friday morning tweet that used quotation marks around the word “bomb.”

“Republicans are doing so well in early voting, and at the polls, and now this ‘Bomb’ stuff happens and the momentum greatly slows — news not talking politics,” Trump wrote. “Very unfortunate, what is going on. Republicans, go out and vote!”
