TRUNALIMUNUMAPRZURE! Joe Biden snaps at aides over press conference confusion.

Biden lost his temper during a press conference, seeming to snap at staffers because he did not know which world leader he was supposed to be introducing next.

The US president appeared on stage with the leaders of Japan, India and Australia on Saturday as part of a two-day summit of their Quad alliance.

But when he was meant to introduce Narendra Modi, the prime minister of India, Mr Biden appeared to snap at his staffers and demanded to know: “Who’s next?”

“I want to thank you all for being here,” Mr Biden said from the stage in Wilmington, Delaware.

He added: “Now, who am I introducing next?”

Mr Biden then shouted: “Who’s next?” This was followed by several seconds of silence.

An announcer cut in to introduce Mr Modi, who approached Mr Biden and shook his hand.

While Mr Biden, 81, has a history of embarrassing gaffes and forgetful moments, Saturday’s hiccup appeared to be due to technical issues rather than his mental acuity.

“By the way, he’s from a small country like ours. A small population like ours,” Mr Biden then said while embracing Mr  Modi, 74. “He’s become a good and decent man. A good friend.”

“He’s become a good decent man?” I’d say Biden’s declining mental acuity may be playing some role here.
