WASHINGTON (Reuters)  - U.S. Senator Bob Corker   the influential Republican chairman of the Senate Foreign Relations Committee  said on Tuesday he will not run for re-election  a blow to a party already struggling to balance divisions between mainstream and more populist wings.
An establishment Republican   Corker  has been criticized from the right  and a conservative activist had already announced a primary challenge. But he was expected to keep the seat  and had amassed a $7.5 million campaign war chest.
 Corker  has ruled out running for governor of Tennessee.
âI have no idea what Iâm going to do. No idea whatsoever â  Corker  said in an interview. But he said he was not leaving out of frustration over deep party divides that have often paralyzed Congress.
 Corker  announced  his  retirement on the day of the failure of the latest Republican effort to repeal former Democratic President Barack Obamaâs healthcare law.
âI am not going to be one of the people who leaves here badmouthing what is one of the greatest privileges of oneâs life â  Corker  said.
He said he realized he was ready to retire on Aug. 24 during a factory groundbreaking in Clarksville  Tennessee  and almost announced his decision at least twice before Tuesday.  Corker  said that he made his announcement now to allow a strong candidate time to enter the Senate race.
 Corker  is the first senator to announce  his  retirement ahead of the 2018 mid-term elections  when one-third of the 100-seat chamber will be up for grabs. Tennessee is a solidly Republican state and the party  which currently holds a 52-seat majority in the Senate  is favored to keep his seat.
In his official announcement   Corker  said that âafter much thought  consideration and family discussionâ over the past year  he and his wife Elizabeth âhave decided that I will leave the United States Senate when my term expires at the end of 2018.â

CLASHES WITH  TRUMP
In August  after Trumpâs much-criticized reaction to violence at a white supremacist rally in Virginia   Corker  told reporters in  his  home state Tennessee that Trump had not been able to demonstrate the âstabilityâ or competence that  he  needed to be successful as president.
After the exchange  the two men had an hour-long meeting at the White House this month that  Corker  has described as a wide-ranging and friendly discussion.
 Corker  will remain chairman of the Foreign Relations Committee until he leaves in January 2019. He said he wanted the panel to address issues including Secretary of State Rex Tillersonâs State Department reorganization  food aid reform  and the fight against human trafficking and modern slavery.
 Corker  said the committee would address the international nuclear agreement with Iran  as Trump faces a mid-October deadline for deciding whether to certify that Tehran is complying with that pact. That decision could force Congress to decide whether to reimpose sanctions.  Corker  would not say whether Trump had decided to certify or not.

President Donald Trump claimed that  Hillary Clinton  “lied many times to the FBI and nothing happened to  her .” In fact  the FBI director told Congress that there was “no basis to conclude  she  lied to the FBI.”
Trump also left the false impression that the FBI deviated from its standard practice by not putting  Clinton  under oath when  she  was interviewed last year about  her  email use while secretary of state. He claimed it was “the most incredible thing anyone has ever seen.” It’s not incredible or even unusual.
Trump  Dec. 4: I will say this:  Hillary Clinton  lied many times to the FBI and nothing happened to  her . Flynn lied and they destroyed his life. I think it’s a shame.  Hillary Clinton   on the Fourth of July weekend  went to the FBI  not under oath — it was the most incredible thing anyone has ever seen.  She  lied many times. Nothing happened to  her . Flynn lied  and it’s like they ruined his life. It’s very unfair.
Trump is referring to the FBI’s three-hour-plus interview with  Clinton  on July 2  2016  near the end of the agency’s investigation into whether  she  or  her  staff mishandled classified information. The investigation stemmed from  Clinton ’s decision to exclusively use a private email account and personal server when conducting official government business.
Three days after the FBI interviewed  Clinton   then-FBI Director James Comey announced that he would not recommend filing charges against  Clinton . He said that  she  and  her  staff were “extremely careless” in handling classified information  but the FBI did not find evidence that their actions were intentional.
The FBI also did not find that  Clinton  lied to the FBI  contrary to Trump’s claim.
After announcing the outcome of the FBI investigation  Comey testified on July 7  2016  before the House oversight committee about his decision not to recommend pressing charges. Chairman Jason Chaffetz specifically asked Comey if  Clinton  lied.
Chaffetz  July 7  2016: Did  Hillary Clinton  lie? Comey: To the FBI? We have no basis to conclude  she  lied to the FBI. Chaffetz: Did  she  lie to the public? Comey: That’s a question I’m not qualified to answer. I can speak about what  she  said to the FBI.
Republicans have long maintained that  Clinton  “lied” to the public about  her  email use. And we have certainly written numerous stories about how  Clinton  provided the public with false and misleading information about  her  email use.
That’s what happened in  Clinton ’s case. On Sept. 2  2016  the FBI released a summary of  Clinton ’s statements to the FBI.
As for  Clinton   the FBI had “no basis to conclude  she  lied to the FBI ” as Comey said. But  under the law  if  she  “knowingly and willfully” made false statements to conceal “a material fact ” then  she  could have been charged with a crime whether  she  was under oath or not.
FactChecking Trump's Criticism of the FBI

Scott Pruitt 's round-the-clock personal security detail  which demands triple the manpower of his predecessors at the Environmental Protection Agency  has prompted officials to rotate in special agents from around the country who otherwise would be investigating environmental crimes.
The EPA's Office of Enforcement and Compliance Assurance has summoned agents from various cities to serve two-week stints helping guard  Pruitt  in recent months. While hiring in many departments is frozen  the agency has sought an exception to hire additional full-time staff to protect  Pruitt .
Hubbard  along with other former and current employees who spoke on the condition of anonymity to discuss internal security issues  said agency investigators in Boston  Denver and other regional offices have been tapped for stints as part of  Pruitt 's security detail.
 Pruitt  has developed a particularly high profile  as well as a divisive one.  His  aggressiveness in trying to reverse a long list of Obama-era policies and  his  repeated questioning of how much human activity contributes to climate change has drawn a steady stream of public vitriol. This outpouring has included a slew of explicit messages on social media  where #PollutingPruitt is a popular hashtag.
While the agency's Office of Inspector General does not discuss the actual number of threats against  Pruitt  or others at the EPA  it did say investigators have opened more cases this fiscal year than in fiscal 2016. Thirty-two percent were aimed at  Pruitt  — including "some very personal  ugly threats " said Patrick Sullivan  the EPA assistant inspector general for investigations — compared with 9 percent directed at his predecessor Gina McCarthy in fiscal 2016.
