High school golf coach resigns after racist tweets to NASCAR driver Darrell Wallace Jr.

A Wisconsin high school golf coach resigned his position after sending racist tweets directed at Darrell “Bubba” Wallace Jr., who is set to become the first African-American driver to compete full-time in NASCAR’s top division since 1971.

Cambridge (Wis.) High School coach Brent Nottestad posted several tweets on Wednesday commenting on Richard Petty Motorsports recently naming Wallace to drive its No. 43 car next season.

One of Nottestad’s tweets, which have since been deleted, included a reference to Wallace’s grandmother, who died last year: “Granny Jan die in a police shooting?” Nottestad also tweeted: “Hey @BubbaWallace. Please quit with, ‘I’m black’ bs. You’re terrible. There are 1423 more credible drivers to get that ride than you.”

The number 1423 is often used by the Southern Brotherhood, the largest white supremacist prison gang in Alabama, according to the Anti-Defamation League.

Nottestad, 42, also wrote in reference to a photo of Wallace posing with a white fan: “Almost looks like going to the zoo.”

Wallace responded to Nottestad’s tweets after the message about his grandmother:

The Cambridge News first reported Nottestad’s resignation. He stepped down Thursday after meeting with school district officials.

“The Cambridge School District was made aware of several offensive comments made on social media by Cambridge High School boys’ golf coach, Brent Nottestad,” Cambridge Superintendent Bernie Nikolay said in a statement. “After a meeting between Mr. Nottestad and school district officials this morning, Mr. Nottestad resigned his position with the district, effective immediately. As this is a personnel matter, no other statements or comments will be forthcoming from the school district.”
