Nixon Wasn't.
But Trump is.
This is nothing less than America's "Enabling Act". You can look that up if you're not familiar.

The Supreme Court on Monday ruled for the first time that former presidents have some immunity from prosecution, extending the delay in the Washington criminal case against Donald Trump on charges he plotted to overturn his 2020 presidential election loss and all but ending prospects the former president could be tried before the November election.
In a historic 6-3 ruling, the justices returned Trump's case to the trial court to determine what is left of special counsel Jack Smith's indictment of Trump. The outcome means additional delay before Trump could face trial.
The court’s decision in a second major Trump case this term, along with its ruling rejecting efforts to bar him from the ballot because of his actions following the 2020 election, underscores the direct and possibly uncomfortable role the justices are playing in the November election.
“Under our constitutional structure of separated powers, the nature of presidential power entitles a former president to absolute immunity from criminal prosecution for actions within his conclusive and preclusive constitutional authority," Chief Justice John Roberts wrote for the court. “And he is entitled to at least presumptive immunity from prosecution for all his official acts. There is no immunity for unofficial acts.”
Roberts was joined by the other five conservative justices. The three liberal justices dissented.
