Documentary producer Michael Moore has an audacious theory concerning why Donald Trump ran for president.

According to Moore, it had been all concerning being jealous of Gwen Stefani.

The oddball theory, that was reportable by The Hollywood Reporter, claims Stefani was creating a lot of on her NBC show The Voice than Trump was on The Apprentice.

So, Trump ran for president as a promotion stunt to prove simply in demand he was.

“He’d been talking about running for president since 1988, but he didn’t really want to be president. There’s no penthouse in the White House. And he doesn’t want to live in a black city. He was trying to pit NBC against another network, but it just went off the rails,” explained Moore.

Moore’s remarks return amid his own promotion tour focused around the release of his newest documentary, Fahrenheit 11/9, that opened at the Toronto Film Fest on Sept. 6.
