John Fetterman, Pennsylvania Democrat running for Senate, has suffered a stroke days before primary - CNBC

John Fetterman, the leading Democrat in the state's high-profile Senate contest, suffered a stroke just days before the primary election but was on his way to a "full recovery," his campaign said on Sunday.

In a 16-second video released by his campaign, a seated Fetterman, speaking clearly, explained that he "just wasn't feeling very well" on Friday and decided to go to the hospital at the urging of his wife.

"The good news is I'm feeling much better, and the doctors tell me I didn't suffer any cognitive damage," he said in the statement.

Questions about Fetterman's health swirled throughout the weekend after he canceled scheduled public appearances Friday, Saturday and Sunday.

"They're keeping me here for now for observation, but I should be out of here sometime soon," he said in the statement.

"Hayley and I are keeping John and his family in our prayers and wishing him a full and speedy recovery," Lamb wrote.

Kenyatta called Fetterman "an incredible family man." "My prayers are with him and his family as he recovers from this stroke," he tweeted.

And on the Republican side, Senate GOP hopeful Mehmet Oz, a heart surgeon, said he has experience treating Fetterman's condition.

"Our campaign isn't slowing down one bit, and we are still on track to win this primary on Tuesday, and flip this Senate seat in November," he said
