Former President Donald Trump said Friday that Fox News staffers helped him write his Al Smith charity dinner speech, in which he cracked jokes and insulted his opponent, Vice President Kamala Harris.

Former President Donald Trump said Friday that “a couple people from Fox” helped write some of the jokes he told at Thursday’s Al Smith charity dinner in New York during an appearance on Fox & Friends that comes as he’s repeatedly bashed the network’s coverage of the presidential race.

The network undercut Trump’s claim—made in a Fox interview—that its people wrote jokes for him to deliver at the Al Smith dinner.
