An armed man wounded a security guard at the Washington DC headquarters of the Family Research Council (FRC) on Wednesday.

The suspect, Floyd Lee Corkins II of Herndon, Virginia, allegedly walked into the lobby of the Christian conservative group and shot the security guard before he was wrestled to the floor. Corkins was in FBI custody Wednesday night.

The Washington Post identified the guard as Leo Johnson and said he was hospitalized in stable condition.

According to the AP, Corkins, 28, had volunteered at a gay community center, The DC Center for the LGBT Community.

Last year, the Southern Poverty Law Center (SPLC) labeled the FRC a hate group, putting it on the same list of groups as the Ku Klux Klan, the Nation of Islam and the Aryan Nations.

The SPLC's Mark Potok told CBN that “the FRC does engage, certainly in our view, in the propagation of known falsehoods in an effort to defame gay people.”

In an appearance on Fox & Friends, Tony Perkins, the president of the FRC, denied he hates gay people.

“No. Not at all,” Perkins said, then quickly added that, “homosexual behavior is harmful not only to society, but more importantly to the individuals who engage in that behavior.”

The Los Angeles Times reported that Corkins was carrying Chick-Fil-A “materials.” The fast-food chain has become a rallying cry for conservatives after its CEO Dan Cathy was criticized for conceding that his company has given millions of dollars to groups opposed to gay rights, including the FRC.

A coalition of twenty-five gay rights groups released a statement condemning the shooting.

“We were saddened to hear news of the shooting this morning at the offices of the Family Research Council. Our hearts go out to the shooting victim, his family, and his co-workers.”

“The motivation and circumstances behind today's tragedy are still unknown, but regardless of what emerges as the reason for this shooting, we utterly reject and condemn such violence. We wish for a swift and complete recovery for the victim of this terrible incident.”
