In his latest embarrassing gaffe, President Biden on Thursday introduced Ukraine President Volodymyr Zelenskyy at the NATO conference in Washington, D.C., as "President Putin."

"And now I want to hand it over to the president of Ukraine, who has as much courage as he has determination," Biden said, before starting to leave the podium. "Ladies and gentlemen, President Putin."

Biden seemed to realize his embarrassing verbal stumble mentioning Russian President Vladimir Putin, and attempted to quickly correct himself.

"He’s going to beat President Putin. President Zelenskyy. I’m so focused on beating Putin," he said. "We got to worry about it. Anyway, Mr. President."

"You are a hell of a lot better," Biden said.

Biden's gaffe comes as his first news conference since his debate debacle that has left the Democratic Party scrambling before the presidential election in November.

Biden has bucked calls to drop out, vowing to remain in the race as his campaign and the White House ramp up his number of public events in an apparent effort to quell concerns the president isn’t up for another four-year term in the Oval Office.

The news conference was highly anticipated, with lawmakers saying that Biden's presser would serve as an "ultimate test" following his disastrous debate two weeks ago with former President Trump.
