In January, Broadwell appeared on Comedy Central’s The Daily Show to promote the book, with her husband Scott in the studio audience. That footage, which includes her challenging host Jon Stewart to a pushup contest, has been making the rounds online and became the most-viewed clip on the show’s website Saturday.

“He has a tenacious will, and he’s just relentless in whatever he does,” Broadwell said of Petraeus.

Stewart also prodded Broadwell for information on whether Petraeus would, as was speculated at the time, someday run for president. Broadwell said her husband would like her to say Petraeus had an interest in being commander in chief because it would help her book sell, but she had to be truthful and admit that wasn’t the case.

Broadwell and Stewart then had a pushup contest to raise money for wounded veterans.
