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

In a statement Sunday, Maryland Gov. Wes Moore praised Biden and thanked him for his decades of service.

"President Biden has dedicated his life and career to serving the American people," Moore wrote. "His legacy of hard work, dedication, optimism, and strength have shaped the trajectory of our nation -- and made us better as a people and as a country."

"This is a man deeply in love with his family, his country, and the promise of America," he wrote. "As a governor, I look to him as an exemplar of true leadership. As an American, I look to him as an embodiment of our shared values of freedom, decency, and patriotism."

The Democratic National Committee has filed an amendment to revise its joint fundraising committees, now named Harris Victory Fund and Harris Action Fund.

These committees, previously named Biden Victory Fund and Biden Action Fund, simply went through name changes and inherited the previous Biden-DNC joint fundraising committees' cash on hand.

Harris Victory Fund had $40 million in cash on hand entering July and Harris Action Fund had $23 million in cash on hand.

President Joe Biden's son, Hunter Biden, is reacting to his father's decision to drop out of the race saying he has looked at his father "in awe" for his entire life.

"How could he suffer so much heartache and yet give so much of whatever remained of his heart to others?" Hunter Biden said in a statement Sunday.

"Over a life time I have witnessed him absorb the pain of countless everyday Americans who he’s given his personal phone number to, because he wanted them to call him when they were hurting. When their last hopes were slipping through their hands," he said.

Hunter Biden said his father's unconditional love has been his North Star as a president and parent

"He is unique in public life today, in that there is no distance between Joe Biden the man and Joe Biden the public servant of the last 54 years," Hunter Biden said.

"I’m so lucky every night I get to tell him I love him, and to thank him. I ask all Americans to join me tonight in doing the same. Thank you, Mr. President. I love you, Dad," he wrote.
