President Trump attempted to fire special counsel Robert Mueller last summer but was stopped after White House counsel Don McGahn threatened to resign
Trump reportedly said Mueller had conflicts of interest in his investigation of Russian interference in the 2016 election, including a dispute over fees at Trump's National Golf Club in Virginia and Mueller's previous employment at a law firm that represent Trump's son-in-law Jared Kushner, according to the Times.
Mueller recently found out about Trump's attempt to have him fired, according to the Times, as his team has begun interviewing top current and former Trump officials.
