On Larry King’s Ora TV show, Mr. Weiner said: “If Hillary were to run, she’d be an amazing candidate, arguably the most qualified candidate in the history of the United States ever to run for president,” The New York Post reported.

Mr. Weiner’s sexting scandal, which began in Congress but ran through his New York City mayoral campaign, reportedly caused some issues for his wife, Huma Abedin, with her high-profile boss, then secretary of state. At one point, media reports suggested that Mrs. Clinton’s camp had issued a scathing choice for Ms. Abedin: Your husband or your job.
