Election 2024 updates: Beshear says Vance 'ain't from Appalachia' at Harris event

Larry Hogan, the former Maryland governor who is running for U.S. Senate, released a statement on X Sunday after President Biden ended his bid for reelection.

"I believe he made the right decision for his family and the country," Hogan, a Republican, said of Biden, adding, "These are dangerous and unprecedented times. He should be commended for putting the country ahead of personal ambition."

"The only way out of this cycle of chaos, divisiveness and dysfunction is to elect principled, common sense and experienced leaders who will focus on the day-to-day challenges facing Americans," Hogan continued.

"We need less palace intrigue, less partisan nonsense, and more decisive action to solve the serious problems facing our nation," Hogan said.

Then-businessman Donald Trump donated $6,000 to Kamala Harris' 2014 California Attorney General reelection campaign, state campaign finance records show.

Trump initially donated $5,000 to Harris’s campaign in 2011, and donated another $1,000 to her campaign in 2013.

Ivanka Trump also donated $2,000 to Harris’s campaign in 2013.

The attack ad put out on Sunday by a pro-Donald Trump PAC attacking Vice President Kamala Harris was made "days" before President Joe Biden announced his decision to drop out of the race, two sources familiar told ABC News.

One source describing the move as "just in case," emphasizing how they had been preparing for this.

One source with the PAC told ABC News that they are viewing the switch from Biden to Harris as a "simple pivot" because Harris "owns all of Joe Biden's failures."

The plan is to frame Harris as a "co-conspirator" in Biden's agenda -- specifically on immigration, as the team has been reporting, the source said.

Former President Donald Trump's running mate JD Vance reacted to President Joe Biden's decision to drop out of the race, calling him "the worst president in my lifetime" and saying they are ready to take on Vice President Kamala Harris.

"Joe Biden has been the worst President in my lifetime and Kamala Harris has been right there with him every step of the way. Over the last four years she co-signed Biden's open border and green scam policies that drove up the cost of housing and groceries. She owns all of these failures, and she lied for nearly four years about Biden's mental capacity--saddling the nation with a president who can't do the job," Vance said in a statement on X.

"President Trump and I are ready to save America, whoever's at the top of the Democrat ticket. Bring it on," Vance said.
