California Rep. Jim Costa became the 22nd member of Congress on Thursday to publicly call for President Joe Biden to end his candidacy for the 2024 presidential election.

"For the good of the country, I think it is time for the President to pass the torch to the next generation to carry on the legacy he started," Costa said in a statement.

"Democrats need to unite and deliver their strongest team to the American people in this election," he said.

"The manifesto lays out Trump’s plan to ban abortion nationwide, slash Social Security and Medicare, and consolidate power so he can rule as a dictator on day one," Biden campaign spokesperson Ammar Moussa said of Project 2025 in a statement.

"His agenda is destructive, drastic, and draconian – and has no place in America. Now, every voter will hear about Trump's Project 2025 and show up in droves this November to defeat it," Moussa said.

The spot is overlayed with audio of different news personalities reporting on Project 2025, including its proposals concerning civil servants and climate change.

The donors who have hit pause on contributing to Biden's campaign are going to hit pause for some time, a Democratic strategist close to Biden’s inner circle told ABC News Thursday.

"It's going to be brutal,” they said. “The headlines are only going to get more intense and money will keep on drying up."

While the three biggest donors to President Biden are still in, and in fact doubling and tripling down, the source claimed it cannot come close to making up for the massive hole.

"It's done," the source said about the Biden campaign’s current strategy. "We will not get the elites back on Biden’s side. The panic has taken over and the stampede is under away."

More than a thousand Black women leaders and allies have signed a letter in support of the Biden-Harris ticket.

In the letter, dated July 17 and addressed to the "Democratic Party leadership," the signatories say they're "writing to share our deep concern and dismay at the lack of unity being displayed by some of our elected democrats and Democratic Party leadership, who are not standing firmly and resolutely for the reelection of President Joseph Biden and his running mate, Vice President Kamala Harris."

"The Biden-Harris administration is running on a solid record of historic legislative accomplishments and a commitment to finish their agenda to improve the lives of all Americans, protect our rights, freedoms and democracy," they continue, in part. "Further, we believe it is unfair and disruptive to judge President Biden for having a bad 90-minute debate performance against a serial liar who wants to destroy our democracy and be a dictator-in-chief."

"History is a great teacher and has taught us that a divided house will fail," they write. "As Black women, we are uniquely aware of the very real threat a second Trump term poses to our country and especially to our community. But this is not a moment to give in to fear. Instead, we must unify around our deep belief in our values and our ability to effectively engage voters and win up and down the ballot in 2024."

They end the letter by saying, "Now is the time for democrats to unite and win."

Some notable signers included actress Vivica A. Fox, former Atlanta Mayor Keisha Lance Bottoms, former Illinois Sen. Carol Moseley Braun and LaTosha Brown of Black Voters Matters.
