Director Rob Reiner reportedly lashed out at then-second gentleman Doug Emhoff last year while the two attended a debate watch party, exclaiming that the country was about to “lose our f—ing democracy” because of President Biden’s disastrous performance.

The scene at the Los Angeles home of James Costos last June is depicted in “Original Sin: President Biden’s Decline, Its Cover-Up, and His Disastrous Choice to Run Again,” the book by Jake Tapper and Alex Thompson published Tuesday. 

“The gathering had originally been planned as a fundraiser for the Biden Victory Fund, but then the debate was scheduled for the same night, so the hosts turned it into a fancy and hopefully fun debate watch party, with people sitting in three or four different rooms,” the authors wrote.

But the star-studded event with a crowd that included Reiner, Emhoff, actor Jane Fonda and Democratic Govs. Andy Beshear, JB Pritzker, and Gretchen Whitmer of Kentucky, Illinois and Michigan, respectively quickly became a “debate watch horror show” as Biden repeatedly and dramatically stumbled against then-former President Trump.

“A few minutes into it, Reiner, in the main living room, stated plainly: ‘We are f—ed!'” Tapper and Thompson wrote of the 78-year-old “When Harry Met Sally” director, one of Hollywood’s most vocal Trump critics.

According to the book, Reiner “became angry. Soon he was venting, standing, full of fury.”

“He seemed to be looking at Emhoff. Daggers.”

“‘We’re going to lose our f—ing democracy because of you!’ Reiner yelled. 

“Because of me? Emhoff thought,” the “Original Sin” authors wrote.

Representatives for Emhoff and Reiner didn’t return ITK’s request for comment.
