We're all familiar with the story of the Nixon White House tapes.
What just happened on Saturday means that are similarities between Trump and Nixon;
1) Nixon initially refused to release the tapes, for two reasons: first, that the Constitutional principle of executive privilege extends to the tapes and citing the separation of powers and checks and balances within the Constitution, and second, claiming they were vital to national security. On October 19, 1973, he offered a compromise; Nixon proposed that U.S. Senator John C. Stennis review and summarize the tapes for accuracy and report his findings to the special prosecutor's office. Special prosecutor Archibald Cox refused the compromise and on Saturday, October 20, 1973, Nixon ordered Attorney General Elliot Richardson to fire Cox. Richardson refused and resigned instead, then Deputy Attorney General William Ruckelshaus was asked to fire Cox but refused and was subsequently fired. Solicitor General and acting head of the Justice Department Robert Bork fired Cox. Nixon appointed Leon Jaworski special counsel on November 1, 1973.
When the Mueller report was released William Barr provided a 4 page summary of the 400+ page report, which Robert Mueller later stated did not accurately reflect the report's findings. Trump, you may recall, tried to fire Mueller twice.
Under Trump, the Saturday night massacre has turned into the Friday night massacre - and they all happened after the news cycle of the day had shut down.
On Friday, February 7, 2020, he fired Lt. Col Alexander Vindman and U.S. Ambassador to the European Union Gordon Sundland, both of whom had testified against Trump in the House impeachment hearings.
On Friday, May 18, 2020, Trump fired State Department Inspector General Steve Linick.
On Friday, August 8, 2020, Postmaster General Louis DeJoy fired two of his top executives, and reassigned 23 others.
On Friday, December 18 (a week for Christmas) former CISA Deputy Director Matthew Travis and top cybersecurity official Bryan Ware resigned after being asked to do so by the White House.
Trump's massacres were not always limited to Fridays.
James Comey was fired on Thursday, May 9, 2017.
His successor, Andrew McCabe, was fired on Wednesday, August 2, 2017 - one day before he was illegible for retirement.
Jeff Sessions was fired on Wednesday, November 7, 2918.
Rex Tillerson was fired on SATURDAY, March 31, 2018. He was fired by a tweet from Trump.
Christopher Krebs, Director of the Cybersecurity and Infrastructure Security Agency was fired by Trump on Tuesday, November 17. 2020
2) What sealed Nixon's fate was the "smoking gun" tape.
On April 11, 1974, the House Judiciary Committee subpoenaed the tapes of 42 White House conversations. Later that month, Nixon released more than 1,200 pages of edited transcripts of the subpoenaed tapes, but refused to turn over the actual tapes, claiming executive privilege once more. The Judiciary Committee, however, rejected Nixon's edited transcripts, saying that they did not comply with the subpoena.
(Trump offered to provide transcripts of his conversation with the Ukrainian president)
Sirica, acting on a request from Jaworski, issued a subpoena for the tapes of 64 presidential conversations to use as evidence in the criminal cases against indicted former Nixon administration officials. Nixon refused, and Jaworski appealed to the U.S. Supreme Court to force Nixon to turn over the tapes. On July 24, 1974, the Supreme Court ordered Nixon to release the tapes. The 8–0 ruling (Justice William Rehnquist recused himself owing to having worked for Attorney General John Mitchell) in United States v. Nixon found that President Nixon was wrong in arguing that courts are compelled to honor, without question, any presidential claim of executive privilege.
(Jeff Sessions recused himself from the Russian investigation)
The White House released the subpoenaed tapes on August 5. One tape, later known as the "smoking gun" tape, documented the initial stages of the Watergate coverup. On it, Nixon and H. R. Haldeman are heard formulating a plan to block investigations by having the CIA falsely claim to the FBI that national security was involved. This demonstrated both that Nixon had been told of the White House connection to the Watergate burglaries soon after they took place, and that he had approved plans to thwart the investigation. In a statement accompanying the release of the tape, Nixon accepted blame for misleading the country about when he had been told of White House involvement, stating that he had a lapse of memory.
(One of the impeachment claims against Trump was obstruction of justice)
Once the "smoking gun" transcript was made public, Nixon's political support practically vanished. The ten Republicans on the House Judiciary Committee who had voted against impeachment in committee announced that they would now vote for impeachment once the matter reached the House floor. He lacked substantial support in the Senate as well; Barry Goldwater and Hugh Scott estimated no more than 15 Senators were willing to even consider acquittal. Facing certain impeachment in the House of Representatives and equally certain conviction in the Senate, Nixon announced his resignation on the evening of Thursday, August 8, 1974, effective as of noon the next day
Since Trump's conversation with Raffensperger is now on tape, could it become Trump's "smoking gun" tape?

According to Jennifer Rubin this morning, what Trump just did is commit ANOTHER impeachable offense.
