Richard Childress, who was Dale Earnhardt's longtime team owner, said of protesting, "It'll get you a ride on a Greyhound bus." Childress says he told his team that, "anybody that works for me should respect the country we live in. So many people gave their lives for it. This is America."
Hall of Fame driver Richard Petty's sentiments took it a step further, saying: "Anybody that don't stand up for the anthem oughta be out of the country. Period. What got 'em where they're at? The United States."
When asked if a protester at Richard Petty Motorsports would be fired, he said, "You're right."
So proud of NASCAR and its supporters and fans. They won't put up with disrespecting our Country or our Flag - they said it loud and clear!— Donald J. Trump (@realDonaldTrump) September 25, 2017
Another team owner Chip Ganassi says he supports Pittsburgh Steelers coach Mike Tomlin's comments. Tomlin said before the Steelers played on Sunday that players would remain in the locker room and that "we're not going to let divisive times or divisive individuals affect our agenda."
