WASHINGTON (AP) - Republican Sen. Thom Tillis of North Carolina collapsed during a Washington, D.C., race Wednesday morning and has been taken away by ambulance.

Around 9:45 a.m., Tillis tweeted out a short video saying he got overheated about 2.5 miles into the race. Tillis said he didn't need CPR and is doing fine.

Tillis, 57, was seen on the ground being administered CPR by bystanders at about the two-mile mark in the three-mile race in Anacostia Park in the southeast part of the city.

North Carolina Democratic Party Chairman Wayne Goodwin issued a statement on Tillis' collapse:

“In spite of our political differences, I and the staff at the North Carolina Democratic Party wish Senator Thom Tillis a full and speedy recovery. Our thoughts and prayers are with him and his family this morning.”
