John Fetterman will win Pennsylvania Democratic Senate primary.

CNN systems, capping a crazy final few days of the campaign after the assistant governor suffered a stroke last week.

Fetterman checked into a hospital in Lancaster, Pennsylvania, on Friday

as he was on his way to a campaign event.

He was found to have had a stroke. Fetterman has been in the hospital ever since,

and he underwent a nearly three-hour surgery on Tuesday to implant a pacemaker that includes a defibrillator.

Fetterman surrounded by his father, brother and his campaign manager

observed the results come in from his hospital, while his supporters gathered in Pittsburgh to cheer the win,

look toward the general election and listen to a speech from Gisele Barreto Fetterman, the candidate's wife.
