Republican Sen. Thom Tillis of North Carolina collapsed during a race in Washington D.C. on Wednesday morning and was soon after taken away by ambulance.
Tillis was participating in the ACLI Capital Challenge Three Mile Team Race at 8 a.m. this morning when he collapsed due to a seizure, CNN reports. Bystanders then administered CPR to the senator, who was then driven out of Anacostia Park by medical officials.
Tillis tweeted a video update from the hospital later that morning, saying he was "doing well" and "looking forward to getting back to work."
Tillis, 57, was leading his own "Team Tillis" race in the annual charity race -- which the AP notes is a popular event among political officials inside the Beltway.
North Carolina's junior senator serves on the Senate Armed Services, Judiciary, Veterans Affairs and Banking, Housing and Urban Affairs committees, as well as the Senate's Special Committee on Aging.
