During an early morning tweet storm Friday, President Donald Trump confirmed he is being investigated for firing former FBI Director James Comey.
I am being investigated for firing the FBI Director by the man who told me to fire the FBI Director! Witch Hunt— Donald J. Trump (@realDonaldTrump) June 16, 2017
The "man" President Trump is referring to is Deputy Attorney General Rod Rosenstein, who wrote a letter recommending Comey be fired.
Rosenstein isn't investigating the President, but he did appoint Special Counsel Robert Mueller to look into Russia's role in the 2016 presidential election, which includes investigating alleged collusion between Trump campaign officials and the Kremlin. Earlier this week the Washington Post released a story reporting Mueller is investigating President Trump for obstruction of justice.
The special counsel overseeing the investigation into Russia’s role in the 2016 election is interviewing senior intelligence officials as part of a widening probe that now includes an examination of whether President Trump attempted to obstruct justice, officials said.
The move by special counsel Robert S. Mueller III to investigate Trump’s conduct marks a major turning point in the nearly year-old FBI investigation, which until recently focused on Russian meddling during the presidential campaign and on whether there was any coordination between the Trump campaign and the Kremlin. Investigators have also been looking for any evidence of possible financial crimes among Trump associates, officials said.
During congressional testimony last week, Comey stated under oath the President was not under investigation by the FBI prior to or after his firing.
Press Secretary Sean Spicer recently confirmed President Trump's tweets are in fact official statements.
