NASCAR is investigating who put a noose in a garage belonging to racecar driver Bubba Wallace. Earlier this month, Wallace, the only Black full-time NASCAR driver, spoke out about Confederate flags being displayed at race events. This led to a Confederate flag ban at NASCAR races. But now less than two weeks later, a noose was left in Wallace’s stall at the Talladega Superspeedway in Lincoln, Alabama. Someone from Wallace’s team noticed the noose and alerted authorities. NASCAR is said to be reviewing surveillance footage to try and determine who left the hateful symbol.

Wallace is also reacting today. He released a statement that read, in part:

“We will not be deterred by the reprehensible actions of those who seek to spread hate. As my mother told me today, “They are just trying to scare you.” This will not break me, I will not give in nor will I back down. I will continue to proudly stand for what I believe in.”
