President Biden endorsed Vice President Kamala Harris after announcing he is dropping out of the 2024 run for re-election. 

"My fellow Democrats, I have decided not to accept the nomination and to focus all my energies on my duties as President for the remainder of my term," Biden posted on X Sunday afternoon 

"My very first decision as the party nominee in 2020 was to pick Kamala Harris as my Vice President. And it’s been the best decision I’ve made. Today I want to offer my full support and endorsement for Kamala to be the nominee of our party this year. Democrats — it’s time to come together and beat Trump. Let’s do this," he continued. 

Biden announced just minutes before he endorsed Harris that he is dropping out of the presidential race. 

BIDEN ENDS BID FOR SECOND TERM IN WHITE HOUSE AS HE DROPS OUT OF HIS 2024 REMATCH WITH TRUMP

"It has been the greatest honor of my life to serve as your President. And while it has been my intention to seek re-election, I believe it is in the best interest of my party and the country for me to stand down and to focus solely on fulfilling my duties as President for the remainder of my term," Biden said in his letter posted to X Sunday afternoon. 

Biden continued that he will address the nation in detail on the decision "later this week." As of Sunday afternoon, Harris has not tweeted about Biden dropping out. 

BIDEN DEFIANTLY CHARGES AHEAD WITH ELECTION RUN DESPITE SPECULATION HE WOULD DROP OUT THIS WEEKEND

He thanked Harris for her work in the administration, but stopped short of offering her his endorsement in his initial letter. Harris has been considered the top choice to replace Biden ahead of the president officially dropping out. 

Democrats' calls had mounted for weeks that Biden should drop out of the race, following his disastrous debate performance on June 27, which put his mental fitness under further scrutiny as he stumbled over his words and appeared more subdued than in previous years. 

As early as Sunday morning, however, Biden allies and the campaign doubled down that the president would not bow out of the race. 

TRUMP GETS BOOST IN POLLS AFTER BIDEN'S BOTCHED DEBATE 

"It is false. And I think that it is false to continue to try to gin up this narrative. Joe Biden has said he is in this race," deputy campaign manager Quentin Fulks said on MSNBC on Sunday. "He is in this race to win it. He is instructing us to continue to carry out a plan to make sure that we are communicating [to as] many voters as possible. Actions speak louder than words, although sometimes, in this case, I wish that our words would speak louder so that people would stop asking this question. But we are doing both. The president has doubled down and said that he is running in this race to win it, and that he is not going anywhere."

Biden dropping out comes as former President Trump was officially nominated as the Republican Party's choice for president. Trump joined the Republican National Convention in Milwaukee, Wisconsin, last week, where he announced Ohio Sen. JD Vance as his running mate and accepted the nomination. 

The RNC was held just two days after an assassination attempt nearly ended Trump's life, leaving him with an injury to his right ear. A shooter opened fire on Trump's rally in Butler, Pennsylvania, last Saturday, injuring Trump and two others, and killing a 50-year-old married dad who was protecting his wife and family from the gunfire.

Trump addressed the shooting in his highly-anticipated RNC speech, while noting "you'll never hear it from me a second time, because it's actually too painful to tell."

"I'm not supposed to be here tonight," he said. "I stand before you in this arena only by the grace of almighty God. And watching the reports over the last few days, many people say it was a providential moment. Probably was."

"For the rest of my life, I will be grateful for the love shown by that giant audience of patriots that stood bravely on that fateful evening in Pennsylvania," he added. 

In the weeks since President Biden's catastrophic debate performance, panicked Democrats have increased pressure on the president to abandon his re-election bid. 

Top Democratic Party officials, megadonors, editorial writers and as many as 37 congressional lawmakers have urged the president to "pass the torch" to a new generation of leadership for fear that Biden cannot defeat Republican nominee former President Trump. 

Biden's top campaign aides have been working damage control with major donors, while the White House — and Biden himself — remain adamant he is the right man to lead the party. 

SCHUMER ‘FORCEFULLY’ TOLD BIDEN HE SHOULD DROP HIS RE-ELECTION BID: REPORT

"Absolutely the president is in this race. You’ve heard him say that time and again," Biden Campaign Chair Jen O'Malley Dillon said Friday on MSNBC's "Morning Joe." 

"I’m not here to say this hasn’t been a tough several weeks for the campaign. There’s no doubt that it has been, and we’ve definitely seen some slippage in support," she added. "But it has been a small movement."

3RD DEMOCRAT SENATOR CALLS ON BIDEN TO STEP ASIDE AS PRESURE ACCELERATES

Twenty-three Democratic governors from across the nation descended on the White House earlier this month to meet with the embattled president, but after the gathering, only Minnesota Gov. Tim Walz, who leads the Democratic Governors Association, New York Gov. Kathy Hochul and Maryland Gov. Wes Moore spoke to reporters to express their support. 

Moore described the meeting with Biden as "honest" and "candid" and said the governors were "going to have his back."

Hochul said Biden was "in it to win it" and that the trio had pledged their support to him "because the stakes could not be higher."

California Gov. Gavin Newsom, who many commentators have proposed as a possible Biden replacement, also took part in the White House meeting and backed the 81-year-old. 

"I heard three words from the President tonight – he’s all in. And so am I," Newsom posted on X on July 3. Newsom also publicly backed Biden immediately after the debate. 

"You don’t turn your back because of one performance," Newsom said after the debate. "What kind of party does that? This president has delivered. We need to deliver for him at this moment."

Illinois Gov. J. B. Pritzker has also publicly backed Biden, as has Arizona Gov. Katie Hobbs and Hawaii Gov. Josh Green. 

Connecticut Gov. Ned Lamont did not outright say Biden should withdraw from the race but told reporters at an event in New Haven July 12 that he is "simpatico" with Rep. Jim Himes, D-Conn., who has called on Biden to drop out.

"I think we’ve come to the same conclusion," Lamont said.
