Amid the flood of reactions calling President Trump's firing of FBI Director James Comey "Nixonian," the Richard Nixon Presidential Library and Museum set the record straight Tuesday night: Nixon never fired the FBI director.

"FUN FACT: President Nixon never fired the Director of the FBI #FBIDirector #notNixonian," the account tweeted.

Democrats made many references to the Saturday Night Massacre when Nixon on Oct. 20, 1973, fired the special investigator who was probing the Watergate scandal. That firing resulted in the resignations of Nixon's attorney general and deputy attorney general.

L. Patrick Gray, who served as acting FBI director under Nixon from May 1972 to April 1973 and was nominated by Nixon in February 1973 but never confirmed, helped Nixon cover up the Watergate scandal. White House officials gave him documents related to the Watergate break-in and Gray shredded them to hide the evidence.

Gray resigned after his actions were discovered.

Mark Felt, the deputy director of the FBI, was the famous "Deep Throat" who helped Washington Post reporters Bob Woodward and Carl Bernstein uncover Nixon's role in the crime.
