'He's lying!: Biden snaps after Fox News fact-checks Trump's false claim

An angry President Joe Biden snapped during a White House news conference after former President Donald Trump was subjected to a fact check from an unlikely source.

Fox News reporter Jacqui Heinrich took to X Monday afternoon first to share that Trump had falsely claimed Biden hadn't reached out to Gov. Brian Kemp — hours after the Georgia Republican praised the president for his outreach — then to share the president's response.

"He’s lying and the governor told him he was lying," Biden said. "The reason I get so angry about it — I don't care about what he says about me — I care what he what he (sic) communicates."

Biden expressed fury that Trump was telling Americans on the ground that they were being ignored as they faced a terrifying and tragic natural disaster that had claimed more than 100 lives as of Monday evening.

"The people that are in need, [it] implies that we're not doing everything possible," Biden said. "It's irresponsible.”

Heinrich, the conservative cable network's White House correspondent, hours earlier reported on the comment about Kemp that so infuriated the president.

"He's having a hard time getting the president on the phone," Trump claimed. "And, of course the Vice President, she's out someplace campaigning looking for money."

Heinrich told her followers this simply was not true.

"This is not accurate," she wrote. "Biden spoke to Gov. Kemp by phone last night...and the [vice president] cancelled campaign events."

Reports confirm Vice President Kamala Harris did call off campaign events in Las Vegas to visit the Federal Emergency Management Agency and receive a brief.

Harris, the Democratic presidential nominee, then addressed Americans to report what she had learned and share her support.

"To all of those of you who are rightly feeling overwhelmed by the destruction and the loss, our nation is with you," said Harris. "I do believe the true character of the nation is revealed in moments of hardship."
