The previous gold standard in Presidential lying was, of course, Richard Nixon. Barry Goldwater, the Republican Presidential nominee four years before Nixon won the White House in 1968, famously called Nixon “the most dishonest individual I ever met in my life.” Writing in his memoirs, Goldwater observed that Nixon “lied to his wife, his family, his friends, longtime colleagues in the U.S. Congress, lifetime members of his own political party, the American people, and the world.”

There have been comparisons between Nixon and Trump since Trump first entered office, but these, too, have escalated in recent months as the President has been shadowed by the threat of the ongoing special-counsel investigation into the electronic break-in of the Democratic National Committee (another eerie Watergate echo) and whether Trump or his campaign colluded with Russia. Trump’s obsession with the special counsel, Robert Mueller, also comes with metrics: he has called the Mueller probe a “witch hunt” on Twitter more than twenty-one times a month on average this spring and summer, compared with an average of just three times a month in the previous nine months.

Another commonality between Nixon and Trump is their obsession with the press as an enemy or, in Trump’s phrase “enemies of the people.” Nixon went so far as to order his White House staff to create an actual “enemies list,” a document with twenty names on it, which was released as part of the Watergate hearings. Reporters like CBS’s Daniel Schorr featured prominently on it. When Sanders announced at her press briefing last week that Trump was considering stripping the security clearances of six former senior U.S. officials who have emerged as scathing Trump critics, many made immediate comparisons to Nixon’s list. “An enemies list is ugly, undemocratic, and un-American,” Adam Schiff, the top Democrat on the House Intelligence Committee, responded.

Only three members of Nixon’s enemies list are still alive. (Ron Dellums, a former member of Congress particularly loathed by Nixon for his anti-war protests and militant civil-rights activism, died on Monday.) I called one of them, Morton Halperin, to ask what he thought of the proliferating Trump-Nixon comparisons. Halperin, who oversaw the writing of the Pentagon Papers and then served on Nixon’s National Security Council staff before breaking with him over the invasion of Cambodia, sued when he found out that Nixon had secretly taped him and others in the White House. Over the years, he has been one of Nixon’s proudest and most persistent enemies. So I was surprised when Halperin insisted, strongly, that Nixon wasn’t nearly as damaging to the institution of the Presidency as Trump has been. “He’s far worse than Nixon,” Halperin told me, “certainly as a threat to the country.”
