A journalism professor at the University of Kansas was placed on administrative leave Friday after posting a comment on Twitter regarding Monday's shooting at the Washington Navy Yard that killed 12 people.

David Guth, an associate professor at the school, went after the National Rifle Association in a Twitter message that read: "#NavyYardShooting The blood is on the hands of the #NRA. Next time, let it be YOUR sons and daughters. Shame on you. May God damn you."

Guth, who said he was writing as a private citizen simply looking to start a debate, has stood by his message.

"I dont apologize for it because I'm not saying in the tweet that I want anybody harmed, and I expanded on it in my blog," Guth told Fox4KC.com. "I defend the NRA's rights first and second amendments and I hope they respect mine."

The Kansas State Rifle Association, however, has called for Guth's immediate dismissal.

"The KSRA will do everything possible to see to the removal of this man," said Kansas State Rifle Association President Patricia Stoneking.

The school's chancellor, Bernadette Gray-Little, made the announcement in a statement Friday about about his "indefinite administrative leave pending a review of the entire situation."
