Joe Biden’s “big boy” news conference was delayed for nearly an hour Thursday evening after a full day of events at the NATO Summit that included a gaffe of monumental proportions.

During a NATO summit press conference earlier in the day, Biden referred to Ukrainian President Zelenskyy as “President Putin” when introducing him to the crowd.

“Now I want to hand it over to the president of Ukraine who has as much courage as he has determination,” Biden said. “Ladies and gentlemen, President Putin!” The stunned audience clapped along despite the flub. Biden quickly caught himself and walked back to the mike. “President Putin? He’s going to beat President Putin. President Zelenskyy,” Biden quipped, amid snickers.

Biden’s much anticipated solo conference comes at the end of a 3-day NATO summit and two weeks after his debate debacle.

Biden hasn’t held very many news conferences that aren’t tied to a foreign leader’s visit or trips abroad where he only gets asked a couple of questions.

His last solo press event was on Nov. 15, 2023.

Biden finally began his presser at 7:28 p.m Eastern.

After his remarks, Biden acknowledged that he had a list of pre-approved reporters to call on. The first reporter from Reuters asked him how he feels about all the calls for him to step down and what concerns he has about Kamala Harris’ ability to beat former President Donald Trump is she were at the top of the ticket.

Biden appeared more rested and alert than he did at the debate, slurring his words less frequently. But he did make a major gaffe at one point, by referring to Kamala Harris as Vice President Trump.

“I wouldn’t have picked Vice President Trump to be vice president [unintelligable] I think she’s not qualified to be President,” he said.
