Biden accidentally called Putin 'President Trump' at his post-summit press conference, then corrected himself

• President Joe Biden on Wednesday started to call his Russian counterpart "President Trump."
• He made the error at a Geneva press conference following a summit with Vladimir Putin.
• He quickly corrected himself, but the internet took notice.

President Joe Biden slipped up after meeting with Russian President Vladimir Putin, whom he accidentally called "President Trump."

Biden quickly corrected himself and moved on from his mistake, which he made Wednesday at a press conference after the two leaders' summit.

They met for cool but cordial discussions in Geneva, where they ceded little ground but agreed on several principles.

They debriefed the media separately after their meeting, and Biden made his error as he was discussing the leaders' priorities in numerous areas of international relations.

"I caught part of President Tru-, Putin's press conference, and he talked about the need for us to be able to have some kind of modus operandi where the Arctic was in fact a free zone," Biden said.

The moment was noted in a tweet from CNN's chief White House correspondent, Kaitlan Collins.

The tweet was widely shared on social media, with some commentators seizing on the view that Donald Trump was inappropriately friendly toward Putin while president.

Ahead of the meeting, Trump in a blog post once again denied any collusion with Russia during his term and also asked Biden to send Putin "my warmest regards!"

It's not the first eyebrow-raising blunder Biden has made - at a March press conference, he called Vice President Kamala Harris "President Harris."

On the campaign trail in 2019, he also acknowledged a "Freudian slip" when he called Trump "President Hump," as The Washington Post reported.
