Q: The Iranian ballistic missile launch that  President Donald Trump  tweeted about Saturday apparently never happened.
On Saturday   Trump  tweeted: âIran just test-fired a Ballistic Missile capable of reaching Israel.They are also working with North Korea.Not much of an agreement we have!â

 Trump  has been criticized a number of times for jumping to conclusions and commenting on Twitter before breaking news reports have been confirmed.
As of Monday night   he  had not deleted the erroneous tweet.
Separately  Twitter Inc. TWTR  -2.30% on Monday explained that it would not block Trumpâs more incendiary tweets because they are newsworthy. Some had complained to Twitter that  his  threats toward North Korean leader Kim Jong Un â which North Korea said Monday it took as a âdeclaration of warâ â violated the companyâs terms of service.

Q: According to Roll Call  the White House sent an email with the subject line  "Condolence Letters Since 20 January 2017" to the Defense secretary's office on the evening of the day  Trump  said  he  had reached out to all the families of soldiers who had been killed.
 Trump 's contact with Gold Star families came under fire this week  after The Associated Press reached out to 43 families and got responses from 20  nine of whom said they had heard from  Trump  and nine of whom said they had not  despite his remark that he had called the families of "virtually everybody" who had died in the line of duty.
Rep. Frederica Wilson of Florida  who was present during the phone call  told the Miami ABC affiliate WPLG on Tuesday that  Trump  had told Myeshia Johnson her husband "knew what he signed up for  but when it happens  it hurts anyway."
Wilson said she was riding in the car with Johnson — who was on her way to the airport to receive her husband's body — when  Trump  called. She then told MSNBC on Wednesday morning that the soldier's widow was "crying the whole time" and that when she hung up the phone  she looked at Wilson and said  "He didn't even remember his name."
Though  Trump  blasted Wilson's account as "totally fabricated " the soldier's mother confirmed to The Washington Post that the congresswoman's account was accurate  adding that  Trump  had "disrespected" her family.
As the controversy continued to unfold  Gold Star families came out en masse to dispute the president's claims. That included Chris Baldridge  whose son  Army Sgt. Dillon Baldridge  died in Afghanistan in June. Baldridge told The Post that  Trump  had offered  him  a $25 000 check  but did not follow through.
"I could not believe  he  was saying that    and I wish I had  it  recorded because  the man  did say this " Baldridge said. " He  said  'No other president has ever done something like this ' but  he  said  'I'm going to do it.'"

Q: Dr. William Schaffner   medical director of the National Foundation for Infectious Disease  a nonprofit organization  told Business Insider that it's hard for experts for sure just how intense this flu season will be.
"Amongst ourselves  we say if you've seen one flu season  you've seen one flu season  " Schaffner  said.
Even so  there are a number of reasons why getting a flu shot is an especially good idea this year   Schaffner  said. Here's his five reasons for everyone who still hasn't gotten the vaccine this fall.
Australia  which heads into summer as the northern hemisphere goes into winter  got hit hard the flu this year. That's especially because of the H3N2 strain of the flu virus. While that still doesn't mean it will definitely be a bad flu season this year  the good news is that the particular strain is a good match to be protected against with  this year's vaccine Schaffner  said.
"I'm afraid we still hear that. No  you cannot get flu from the flu vaccine  " Schaffner  said. According to the CDC  flu shots are either made using an inactive virus that aren't infectious or a vaccine that doesn't contain the virus at all.
"We can do an awful lot of good with this pretty good vaccine  because it's the one we have to use today  " Schaffner  said.
There are plenty of ways to get vaccinated for free. Most insurers cover it as a preventive treatment  and Medicare covers the shot entirely. "It's easy  it's quick  it's covered by insurance  " Schaffner  said. Plus  most drugstore clinics  including Walgreens and CVS have the vaccines available  so you don't even have to go to a doctor's office.
