Michael Moore has a theory about how Gwen Stefani might have unwittingly played a role in Donald Trump becoming the President of the United States, and he pitched his theory to The Hollywood Reporter ahead of the release of his new documentary, 'Fahrenheit 11/9.'

The provocative documentarian — who last year performed an anti-President Trump show on Broadway — claims that when Trump, then a host of NBC’s 'Celebrity Apprentice,' found out that Stefani’s paychecks as a coach on the network’s show 'The Voice' were bigger than his, he was determined to prove that he was worth more to NBC with a political run, which he apparently never intended to win.

"He'd been talking about running for president since 1988, but he didn't really want to be president,” says Moore.

“There's no penthouse in the White House. And he doesn't want to live in a black city,” Moore added. “He was trying to pit NBC against another network, but it just went off the rails."

Moore gave no indication on what he based his claims about the 'Hollaback Girl' singer and Trump, but he's not the first to suggest that Trump ran for the presidency without any intentions of winning.  It was one of many explosive allegations in Michael Wolff's popular book 'Fire and Fury: Inside the Trump White House'.

According to Wolff, Trump's plan all along was to lose, but build a bigger audience in the process, because Trump wanted to launch his own television network. But we all know how that actually turned out.

Moore's new documentary, 'Fahrenheit 11/9', presents a critical view of Trump's presidency and kicks off the Toronto International Film Festival on Thursday, Sept. 6. Watch the trailer for the documentary below.
