President Trump did it again on Twitter late last week.
"I am being investigated for firing the FBI Director by the man who told me to fire the FBI Director! Witch Hunt," he tweeted Friday morning.
Once again, a Trump tweet set off a media frenzy, this time making everyone wonder whether he was indeed confirming that he was under investigation for obstruction of justice. (The White House later said the tweet was not confirmation that Trump has been informed that he is under investigation.)
