Before he ran for president, decrepit Joe Biden bitterly criticized President Donald Trump as “a fucking asshole,” claiming he “isn’t really an American president,” according to a new book.

The book Peril, by Bob Woodward and Robert Costa, cited Biden’s political adviser Ron Klain who was in a meeting with Biden when the latter spoke to his team about running for president in 2020. “This guy just isn’t really an American president,” Klain said Biden complained.

The book also recounts other incidents of Biden’s views on Trump behind the scenes. After Biden was inaugurated as president, he walked into one of the rooms in the White House where Trump had set up a large video screen to practice golf. “What a fucking asshole,” Biden commented.

The Biden team even hated using Trump’s name, the book reports, warning each other to avoid the “T word” in their daily routines.

Even today, Trump apparently continues to live rent-free in what remains of Biden’s mind. In September, Biden appeared aware that Trump had spoken about entering the boxing ring with the president as part of a promotional interview for a fight.

“I mean — you know. I should be so lucky,” Biden told reporters. “You know what I mean?”
