Democratic Senate Majority Leader Chuck Schumer praised President Biden's legacy and said he "put the country, his party, and our future first" with his decision Sunday.

“Joe, today shows you are a true patriot and great American,” he said.

Schumer's statement comes days after sources told ABC News that Schumer privately urged Biden to drop out of the race.

Schumer had a blunt conversation with Biden, sources said, making the case it would be best if Biden dropped out of the 2024 presidential race.

Vermont Sen. Bernie Sanders reacted to Biden's decision to end his bid for reelection on Sunday.

"Joe Biden has served our country with honor and dignity," Sanders wrote in a statement on X.

"As the first president to ever walk on a picket line with striking workers, he has been the most pro-working class president in modern American history," Sanders continued.

Sanders ran against Biden for the Democratic nomination in the 2020 presidential race.

"Thank you, Mr. President, for all you’ve done," Sanders wrote.

Former Speaker of the House Nancy Pelosi called President Joe Biden "a patriotic American who has always put our country first."

"His legacy of vision, values and leadership make him one of the most consequential Presidents in American history. With love and gratitude to President Biden for always believing in the promise of America and giving people the opportunity to reach their fulfillment," Pelosi said in a statement Sunday.

"God blessed America with Joe Biden’s greatness and goodness," Pelosi said.

Bill and Hillary Clinton endorsed Vice President Kamala Harris for president, saying in a statement that they would "fight with everything we’ve got" to elect her.

"We are honored to join the President in endorsing Vice President Harris and will do whatever we can to support her," they wrote.
