On the last day of the 1996 Democratic Convention in Chicago, Mr. Morris resigned as chief campaign strategist for President Clinton’s re-election bid because The Star, the sister publication of The National Enquirer, revealed Mr. Morris’s affair with a prostitute who claimed he had a penchant for sucking her toes. The National Enquirer followed that bombshell with news of another mistress and a love child in Texas.

When he quit the Clinton campaign, Mr. Morris issued a statement: “I will not subject my wife, family or friends to the sadistic vitriol of yellow journalism. I will not dignify such journalism with a reply or an answer. I never will.”

Now he is the chief political commentator and correspondent for The National Enquirer.

Mr. Morris said he didn’t bear ill will against either of the scandal sheets that brought him down. “Listen, the story was accurate,” he said quietly. “It changed my life completely, and it made my marriage much stronger.”

In a zigzag career, Mr. Morris has had many highs and lows and reboots. In recent years, he has had many foreign clients, including the nationalist Viktor Orban, the prime minister of Hungary; in 2002 and 2004, he did media strategy in Britain for the party of Nigel Farage, a cheerleader for the so-called Brexit.

Mr. Morris has made a living denouncing Bill and Hillary Clinton in books, columns, blogs and television appearances. In a video on his website, Mr. Morris argues that Mrs. Clinton’s email scandal still has legs, saying “Indict Hillary for lying to Congress!”
