President Trump tweeted Thursday that the Russia investigation had nothing to do with why he fired FBI Director James Comey even though the president told the Russians and Lester Holt the exact opposite in the days following Comey's dismissal on May 9, 2017.

In addition, Trump's lawyer, Rudy Giuliani, said on television on May 2, 2018 that the president fired Comey because the FBI Director would not say the president was not a target of the Russia investigation.
