Sen. Thom Tillis collapses during charity race, receives CPR before being taken away by ambulance

This story has been updated. 

North Carolina Republican Sen. Thom Tillis reportedly collapsed during a race in Washington, D.C., Wednesday morning and was rushed to an unnamed hospital by ambulance, according to The Associated Press.

Tillis, 57, collapsed 15 to 20 minutes into the ACLI Capital Challenge Three Mile Team Race in Anacostia Park, the AP reported, and was seen being given CPR.

The senator was leading his own Team Tillis in the annual race that is popular among many politicians. All proceeds generated by the race are donated to charity. Tillis tweeted a photo of himself and Team Tillis just before the start of the race.

Sources say that Tillis was unconscious but was revived and breathing by the time the ambulance had arrived.

Tillis was elected in 2014 and is the junior senator of North Carolina.

After learning of Tillis' collapse, other lawmakers began sending well wishes.

UPDATE: Tillis' Twitter account just tweeted this video message from Tillis, indicating that his condition is apparently not serious despite the scare.
