Governor's full statement"On Friday, I wasn’t feeling well, so I went to the hospital to get checked out. I didn’t want to go – I didn’t think I had to – but Gisele insisted, and as usual, she was right. I hadn't been feeling well, but was so focused on the campaign that I ignored the signs and just kept going. 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. Fortunately, Gisele spotted the symptoms and got me to the hospital within minutes. The amazing doctors here were able to quickly and completely remove the clot, reversing the stroke, they got my heart under control as well. It's a good reminder to listen to your body and be aware of the signs."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. They’re keeping me here 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. There’s so much at stake in this race, and I’m going to be ready for the hard fight ahead."But 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. Thanks for all the support, and please get out there and vote."The kick-ass staff and doctors at Penn Medicine Lancaster General Health are working closely and constantly with our campaign team to ensure there is only one voice speaking on behalf of John. They have been extremely supportive and helpful over the course of the past couple days."Stay with WGAL News 8 for updates on this developing story.Candidates react to newsOther Pennsylvania candidates and current Gov.
