Sen. Thom Tillis, R-N.C., collapsed during a race in Washington, D.C., on Wednesday morning and was taken away in an ambulance.
The Associated Press reported that the Republican senator had received CPR, but Tillis said from a hospital bed that he had not.
"Hey everybody. I'm fine. Just running about 2 and a half miles in, got overheated. No CPR, no special measures, just checking me out. See you back on the hill," Tillis said in a video posted on Twitter.
I'm doing well. Looking forward to getting back to work. Thanks for all of your prayers and well wishes. #CapChallenge pic.twitter.com/uQGQp85qzR— Senator Thom Tillis (@SenThomTillis) May 17, 2017
Less than an hour before the incident Tillis had tweeted a photo of himself at the American Council of Life Insurers race.
