Sen. John Fetterman, D-Pa., doubled down on his support for President Biden after his highly criticized debate performance last month. 

Fetterman told Fox News host Jesse Watters Wednesday on "Jesse Watters Primetime" he realizes Biden isn’t as sharp as he was a few years ago, but it doesn’t change his support for the commander-in-chief.

"I really don't think I've seen anything that makes me want to change that," he said. "I'm not following him blindly, but I do fundamentally believe he's been a great president and I do believe ultimately he can prevail."

BIDEN REMAINS DEFIANT AS HE SETS PRIMETIME INTERVIEW WITH NBC'S LESTER HOLD

Biden has refuted calls from his own party to step down from the 2024 race, saying in a letter to House Democrats Monday that he’s the best candidate who can beat former President Trump in November. 

Nine House Democrats and one Democratic senator have called on Biden to withdraw from the 2024 race since his disastrous performance at the CNN Presidential Debate in Atlanta, according to a tally from The Associated Press.

Fetterman admitted to Watters he only saw parts of the Biden-Trump debate, but there was no question that the president had a "bad night."

He said he’s spent a year with Biden at different events across Pennsylvania, and to him, he was "normal" and "engaged."

"He was actually very popular, and people were eager to have a selfie and those kinds of thing[s]. So, I really want to remind everybody that Joe Biden has done a really good job as president, and I fundamentally am going to remain loyal to that," Fetterman added.

The former Braddock mayor said at the end of the day, debates don’t really mean much and conversations about Biden stepping down should stop.

"Joe Biden is going to be our guy, and it's going to be rough, and it's uncertain, but it's going to be very close as well, too," he told Watters.

"I refuse to turn our back on a great president and I know people watching this might disagree that he hasn't been a great president, but I do believe he was. And I think loyalty is really one of the last... It's one of the last currencies in this lousy business."
 

Fox News host Jesse Watters argues Nancy Pelosi and other leading Democrats are starting to turn on President Biden amid mounting calls for him to drop out of the 2024 presidential race on "Jesse Watters Primetime."

BIDEN ADVISERS TO JOIN SENATE DEMS FOR SPECIAL MEETING AMID SWELLING CONCERNS

JESSE WATTERS: Day three of the Joe Biden hostage crisis, as we witness what political insiders are calling a "bomb drop" in Washington, the first shots fired in the Democrat's civil war. It was Nancy Pelosi who pulled the trigger on Biden's favorite morning show.

Biden decided he's running, and Nancy Pelosi said he hasn't decided yet, but time is running out. One senior Democrat aide said she knows he's watching. She's not an idiot. She chose those words carefully. Another one said it was a shot in the arm, Biden thought he had until Saturday before Democrats send in the SWAT team. But Pelosi, the sharpshooter, [was] taking aim early.

And just breaking tonight, the first Democrat member of the Senate is calling on Biden to withdraw from the race, Senator Peter Welch of Vermont. And Senate Majority Leader Chuck Schumer is telling donors he's open to dumping Biden. So Nancy and Chuck have formed an alliance, and Biden's countering by sending his staff to Capitol Hill tomorrow to beg. 

But an anonymous Democrat senator calls it a waste of everyone's time if Biden can't even come make the case himself. Biden's done negotiating. CNN reports that Biden is done talking about it, and he's staying in the race. But this is a delicate hostage negotiation. And if Biden thinks only God can convince him to bow out, he should prepare for this.
