President Trump claims he is being investigated because he fired FBI Director James Comey. In a morning tweet, Trump said he is being investigated by "the man who told me to fire the FBI Director." That appears to be a reference to Deputy Attorney General Rod Rosenstein. Trump again called the Russia investigation a "witch hunt." Rosenstein hired former FBI Director Robert Mueller as special counsel after Trump fired Comey. The investigation of Russian interference in the presidential election includes allegations of collusion between Moscow and members of Trump's campaign team. The President is reportedly under investigation for obstruction of justice.
