NASCAR drivers reacted with horror today upon the news that more than 50 people have been killed and more than 400 injured during a country music concert in Las Vegas. The shooting happened at an outdoor country music festival starring Jason Aldean -- a long-time friend of NASCAR.
NASCAR drivers began taking to social media on Monday morning.
Moreover, the Las Vegas 350 at Las Vegas Motor Speedway was just held on Saturday and several from NASCAR were still in town when the shooting happened.
The New York Times called it one of the worst mass shootings in U.S. history.
Aldean has helped NASCAR launched a video game, has performed before NASCAR races, and his music company has partnered in the past with Chip Ganassi Racing.
The shooting happened about 10 p.m. local time (1 a.m. EST) when a gunman, identified as Stephen Paddock, 64, of Mesquite, Nevada, began firing from the 32nd floor of the Mandalay Bay hotel. Authorities, in an early morning press conference, said they have no motive yet.
After police broke down his hotel room door, they found Paddock dead.
