President Joe Biden once again added to growing concerns on Thursday that he is not mentally fit for office when he introduced Ukrainian President Volodymyr Zelensky as Russian President Vladimir Putin during a press conference at the NATO summit in Washington.

The screw up comes as Biden has faced growing calls to quit his re-election campaign from members within his own party and throughout the media over the last two weeks following his disastrous debate performance against former President Donald Trump.

“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 mistake is even more embarrassing considering that Putin started a major war in Europe with his invasion of Ukraine two years ago.

A House Democrat responded to the clip by telling ABC News: “This is the greatest introduction of all time … It would be like introducing Winston Churchill and saying ladies and gentlemen Hitler.”

After walking away from the microphone for a brief moment, Biden realized that he screwed up Zelensky’s name and stepped back up and offered an excuse for why he messed it up.

“President Putin? We’re gonna beat President Putin,” he said. “President Zelenskyy! I’m so focused on beating Putin. We got to worry about it — anyway, Mr. President.”

Following the mistake, a longtime adviser to Biden told CNN: “I just think there is an unfortunate inevitability to all this. I am sad because I have known him a long time and he is a good man. I am angry at his inner circle who have not served him well and at times committed malpractice in their service. And I am frustrated at the family for not expanding the circle so there would be a truth teller or two in their midst. They created a perfect storm of an echo chamber and it is biting them all in the a*s.”

Rep. Marie Gluesenkamp Perez (D-WA) suggested on Thursday that President Joe Biden not only quit his re-election campaign but to also resign immediately from his role as president following his disastrous debate performance against former President Donald Trump.

“I’ve spent the past two weeks listening to my constituents express their concerns about the President’s age and health,” she said in a statement. “Like most people I represent in Southwest Washington, I doubt the President’s judgement about his health, his fitness to do the job, and whether he is the one making important decisions about our country, rather than unelected advisors.”

“Americans deserve to feel their president is fit enough to do the job,” she added. “The crisis of confidence in the President’s leadership needs to come to an end. The President should do what he knows is right for the country and put the national interest first.”

Perez’s statement comes as at least 17 major Democrats have called on Biden to quit his re-election campaign in recent days as polls for the most part have shown that the race has shifted in Trump’s favor.

Numerous leaks have come out of the Biden administration and top Democrat circles over the last two weeks about the dire shape that Biden is in and how his family and top aides sought to cover up his condition by limiting access to the president and maintaining strict protocols during his public appearances.

During this time, Trump has largely removed himself from the news cycle in order to keep focus on Biden’s cognitive decline which has resulted in more pressure being put on the 81-year-old president to end his campaign.
