Senator Thom Tillis Collapses During Race

The North Carolina senator posted a video to Twitter from the hospital, cheerfully saying he was "fine."

Sen. Thom Tillis (R-N.C.) is recovering after he collapsed while running a race in Washington, D.C., Wednesday morning.

Tillis posted a video to Twitter from the hospital, assuring viewers he was “fine.” He said he got overheated about two and a half miles into the American Council of Life Insurers Capital Challenge, a three-mile team race in Anacostia Park.

“No CPR, no special measures, just checking me out,” Tillis said. “See you back on the Hill.”

It was initially reported that Tillis had a seizure during the race, but Tillis’ office later confirmed to HuffPost that the senator collapsed as a result of overheating and dehydration.

Tillis had tweeted about the race earlier Wednesday.

WUSA9’s Debra Alfarone tweeted a photo of Tillis being helped during the race.

Tillis’ colleagues, including Sen. Marco Rubio (R-Fla.), were quick to offer up their prayers for the senator.
