“Real Time” host Bill Maher roasted President Donald Trump on Friday night over his repeated flip-flopping on key policy decisions.

“We’ve weathered in this country Hurricane Harvey and Hurricane Irma, and now we’re back to worrying about Shitstorm Donald,” joked Maher during his opening monologue.

With his ever changing stances on various important issues, Maher said the commander in chief probably “thinks he’s being bipartisan.”

But “this is not bipartisan,” said Maher. “This is bipolar. I don’t know if he knows what he wants.”

Maher also poked fun at angry right-wingers who have reportedly been burning their “Make America Great Again” caps in protest over Trump’s possible immigration deal with Democratic leaders.

It’s “very scary,” said Maher, “because it means they’ve discovered fire. Tools could be next.”
