Bubba Wallace is clearly upset by the backlash over the results of the FBI investigation into the alleged noose in his garage at Talladega ... saying, "I'm mad because people are trying to test my character."
The FBI and NASCAR both say the rope found in Bubba's garage in Alabama on Sunday was a rope pull that was fashioned into noose ... and it had been in the garage stall since 2019.
Investigators concluded it was NOT made as a threat to Wallace -- and the case will no longer be pursued as a hate crime.
