A sociology professor at the College of Southern Nevada shot himself in the arm with a .22 pistol in protest of President Donald Trump.

The professor’s wounds are not life-threatening, but he now faces multiple charges for bringing the gun onto campus to carry out the protest.

The Las Vegas Review-Journal reports that the professor, Mark J. Bird, shot himself in a bathroom on campus, then stumbled out, “bleeding, before he collapsed.”

Bird taped a $100 bill to the mirror prior to shooting himself as a tip to the janitor for cleaning up the mess.

Bird was hired by the college in 1993 and is currently a professor emeritus.

The police report on the incident notes that “Bird said he had shot himself in protest of President Donald Trump.”

Bird faces charges for firing a gun in a gun-free zone and also for “carrying a concealed weapon without a permit and possessing a dangerous weapon on school property.”
