Biden says his health is not hurting his ability to campaign for Kamala Harris: 'I have no serious problem'

• Biden addressed questions regarding his health following his exit from the 2024 race.
• The president told CBS News he had "no serious problem" and was just sick during the June debate.
• Biden said he was ready to join the campaign trail to stump for Vice President Harris' campaign.

In an interview that aired Sunday, President Joe Biden rebuffed speculation over his health and said he was ready to stump for Vice President Kamala Harris.

Biden, who stepped aside as the Democratic presidential nominee last month after a poor debate performance in June, touched on his condition while laying out his plans to aid Harris' presidential campaign.

"I had a really, really bad day in that debate because I was sick, but I have no serious problem," Biden told CBS News on Sunday.

Biden then pivoted to Harris' race, noting that he looked forward to stumping for the vice president in Pennsylvania , a critical battleground state for both Harris and former President Donald Trump.

"I was talking to Governor [Josh] Shapiro, who's a friend. We have to win Pennsylvania, my original home state," he said. "He and I are putting together a campaign tour in Pennsylvania."

"I'm going to be campaigning in other states as well, and I'm going to do whatever Kamala thinks I can do to help the most," he continued.

Since ending his campaign, the president hasn't been almost entirely absent from the spotlight.

Biden earlier this month oversaw a historic and complex prisoner swap with Russia and other countries that freed at least 24 people. Three Americans — the Wall Street Journal reporter Evan Gershkovich, the former US Marine Paul Whelan, and the journalist Alsu Kurmasheva — were released as part of the exchange. It was the culmination of months of negotiations.

When the Americans landed at Joint Base Andrews in Maryland shortly after their release, both Biden and Harris were on hand to greet the group.

During his CBS interview, Biden said he hoped Americans would remember him for proving that "democracy can work."

"It got us out of a pandemic," he said. "It produced the single greatest economic recovery in American history. We're the most powerful economy in the world. We have more to do."
