The Justice Department is reportedly preventing Senate investigators from speaking with two FBI officials who may provide first-hand testimony about Donald Trump’s firing of ex-FBI director James Comey.
It is the latest sign that Special Counsel Robert Mueller could be investigating the sacking as part of his Russia-related probe.
Mr Mueller is trying to determine if Mr Trump’s campaign advisers colluded with the Russian government to influence the 2016 presidential election. That investigation also reportedly involves a probe into whether the President obstructed justice when he allegedly asked Mr Comey to drop an inquiry into Mr Flynn’s possible ties to Russia.
Multiple congressional committees are also investigating Russia’s meddling last year’s presidential race.
It was reported last week that Mr Mueller hopes to speak with several of the President’s current and former top aides who were privy to episodes relevant to his investigation.
Mr Mueller is said to have alerted the White House that he wants to interview former press secretary Sean Spicer, ex-Chief of Staff Reince Priebus, and current communications director Hope Hicks, among others, according to the Washington Post.
Each of the advisers are alleged to have been involved or aware of internal discussions that have drawn the interest of Mr Mueller during his investigation, including the conversations that led to Mr Trump’s firing of ex-FBI chief James Comey and the dismissal of former National Security Adviser Michael Flynn.
