Chris Christie is set to play a major role in Donald Trump's administration if the presumptive Republican nominee wins in November.

But is the governor also the billionaire businessman's errand boy?

In a piece for The New Yorker about GOP elites struggling over whether to get behind Trump or resist the controversial nominee, reporter Ryan Lizza highlighted Christie's staunch support for Trump with an anecdote about Christie running chores for his one-time opponent.

Lizza wrote Christie "has transformed himself into a sort of manservant, who is constantly with Trump at events."

"One Republican told me that a friend of his on the Trump campaign used Snapchat to send him a video of Christie fetching Trump's McDonald's order," Lizza wrote.

The story's accuracy, noted in a parentheses, is based on unnamed source's anonymous friend.

Brian Murray, a spokesman for Christie, said the story is wrong.

"We categorically deny this ridiculous, completely invented scenario, which the writer attributed to an unnamed source's anonymous friend," Murray said. "The fact the writer relegated this bit of sleaze between parentheses certainly indicates he knew it was pure trash that had to be carefully separated from the rest of the story."
