The author of the New Yorker report about New Jersey Gov. Chris Christie fetching McDonald’s for then-candidate Donald Trump said that former campaign aide Sam Nunberg's claim he was the source is false.

"This is incorrect," tweeted Ryan Lizza on Friday. "Sam Nunberg was not the source of The New Yorker’s anecdote about Chris Christie and McDonald’s."

In a Politico piece published Friday, Nunberg said he made up the story to embarrass Christie.

“The sad reality is that it was believable,” Nunberg claimed.

Lizza later said he "unfortunately" was not contacted for the Politico piece.

In June 2016, Lizza reported a Republican told him “a friend of his on the Trump campaign used Snapchat to send him a video of Christie fetching Trump’s McDonald’s order.”

Christie’s office denied the story, which had gone viral, calling it a “bit of sleaze” and “pure trash.”
