Rep. Phil Roe (R-Tenn.) performed CPR and administered defibrillation on a man in cardiac arrest in a North Carolina airport on Tuesday, Roe’s office confirmed.

Roe rushed to an unidentified man’s aid in the Charlotte airport Tuesday morning, performed CPR, and used the emergency medical technicians’ equipment in order to shock the man’s heart, according to Roe’s office. 

Roe was able to restart the man’s heart.

“I bet the guy wasn’t down probably 30 seconds before Phil was taking care of him. They gave him CPR for like 5 or 6 minutes. They pumped his chest pretty good. It was work, it was pretty intimidating to watch,” Rep. Mick Mulvaney (R-S.C.), Roe’s traveling companion, told The Daily Caller.

Mulvaney said he saw the man’s heartbeat flatline.

“The guy was dead. There’s no question,” Mulvaney said. “This guy is alive because of Phil Roe and a couple other very important people at the airport.”

Roe earned his medical degree from the University of Tennessee. He served two years in the U.S. Army Medical Corps,and practiced as an obstetrician before running for office.
