Pennsylvania Lt. Gov. John Fetterman, who is running for the state’s Democratic Senate nomination, said in a statement Sunday he's recovering from a stroke he suffered on Friday.

What he's saying: "I hadn't been feeling well but was so focused on the campaign that I ignored the signs and just kept going," Fetterman wrote. "On Friday it finally caught up with me. I had a stroke that was caused by a clot from my heart being in an A-fib rhythm for too long."

• “The good news is I’m feeling much better, and the doctors tell me I didn’t suffer any cognitive damage. I’m well on my way to a full recovery. So I have a lot to be thankful for."

What's next: Fetterman on Sunday said he's being kept at Penn Medicine Lancaster General Hospital "for now for observation, but I should be out of here sometime soon."

• "The doctors have assured me that I’ll be able to get back on the trail, but first I need to take a minute, get some rest and recover," he added. "There’s so much at stake in this race, and I’m going to be ready for the hard fight ahead."
• It is unclear when Fetterman will return to the trail.

On Tuesday, the day of the Pennsylvania primary, Fetterman's campaign said he will have a standard procedure to implant a pacemaker with a defibrillator.

• "It should be a short procedure that will help protect his heart and address the underlying cause of his stroke, atrial fibrillation (A-fib), by regulating his heart rate and rhythm."

The big picture: Fetterman is the front-runner for Tuesday's Democratic primary, and the stroke has kept him off the trail the final weekend before the contest.

• He was supposed to host a meet-and-greet in Lancaster County on Friday morning, per the New York Times, but his spokesperson said at the time the campaign had canceled the event because Fetterman was feeling unwell.
