They know it's over.

Secretary of Defense Lloyd Austin, Secretary of State Antony Blinken and National Security Advisor Jake Sullivan winced as Joe Biden called Kamala Harris "Vice President Trump" during Thursday night's "Big Boy" press conference.

Joe Biden Thursday evening was nearly one hour late to his "Big Boy" press conference and it was a total dumpster fire.

Old Joe botched the first question when he called Kamala Harris "Vice President Trump."

This was literally right after Joe Biden called Ukrainian President Volodymyr Zelensky, "President Putin."

"I wouldn't have picked Vice President Trump to be Vice President if I didn't think she was not qualified to be president," Biden said after a reporter asked him about Kamala Harris being at the top of the ticket.
