Crockett Keller is a firearm-safety instructor in Mason, Texas.

Last Wednesday he held an all-day course at his business, Keller's Riverside Store, to give people the training for a concealed hand gun permit and allow them to take the proficiency test at the end of the day.

But the course wasn't for everyone: Crockett ran radio ads explaining that Muslims and anyone who voted for President Obama were not welcome in his class.

Here's the full 60-second radio ad:

He said, "If you are a socialist liberal and/or voted for the current campaigner-in-chief, please do not take this class."

His logic is that the law requires that anyone who applies for a gun permit must be capable of making good decisions and a vote for Obama proves you aren't capable of that.

That's not all. Muslims couldn't take the class because, quote, "You cannot be a true American. Why should I arm these people to kill me?"

The Texas Department of Public Safety is conducting an investigation, and Crockett may end up losing his gun-instructor certification.
