Pennsylvania Democratic Senate front-runner John Fetterman says he suffered a stroke

Pennsylvania Democratic Lt. Gov. John Fetterman, the Democratic front-runner in the state's U.S. Senate race, announced on Sunday he suffered a stroke over the weekend, but he is on his "way to a full recovery."

Fetterman, 52, posted a video of himself with his wife, Gisele. He said he was not feeling well on Friday and at the urging of his wife, he went to the hospital. 

"I'm well on my way to a full recovery. So I have a lot to
be thankful for. They're keeping me here for now for observation, but I should be out of here sometime soon," Fetterman, who is still at Penn Medicine Lancaster General Hospital, said in a press release.

"John had a stroke that was caused by a clot from his heart beating in an irregular rhythm for too long," Gisele Fetterman said in the video posted on Twitter. 

"Fortunately the amazing doctors here were able to completely clear the clot and entirely reverse the stroke. They also got his heart under control," Pennsylvania's second lady said.

The Democratic candidate insisted that his "campaign isn't slowing down one bit."

"[W]e are still on track to win the primary on Tuesday, and flip this Senate seat in November," Fetterman added.
