A Herndon man accused of shooting a security guard at the downtown D.C. headquarters of the Family Research Council on Aug. 15 was indicted Wednesday on federal and District charges in the incident, in which he allegedly decried the organization’s political views before pulling out a pistol.

A grand jury indicted Floyd Lee Corkins II, 28, on a federal charge of transporting a firearm and ammunition across state lines and D.C. offenses of assault with intent to kill while armed and possession of a firearm during a violent crime.

Corkins is scheduled to be arraigned Friday.

The guard, Leonardo R. Johnson, 46, of the District was shot once in the arm but managed to subdue Corkins and wrestle away his gun in the lobby of the council’s office, in the 800 block of G Street NW, police have said.

Johnson is out of the hospital but not back at work, council spokesman Jeff Ford said.

An FBI affidavit quotes Corkins telling the guard about 10:45 a.m., “I don’t like your politics,” as he pulled a 9mm Sig Sauer pistol from a backpack.

In the backpack, court documents say, police found 50 rounds of ammunition and 15 Chick-fil-A sandwiches which, combined with the suspect’s statement, added a political dimension to the shooting.

The head of the Atlanta-based fast-food chain has spoken out against same-sex marriage, a stance also taken by the Family Research Council. Corkins had been volunteering at a U Street NW support center for the gay community.

The FBI affidavit says agents interviewed Corkins’s parents, who said their son “has strong opinions with respect to those he believes do not treat homosexuals in a fair manner.”

The Family Research Council’s Web site says it deals in issues of faith, family and freedom; opposes abortion and euthanasia; and considers homosexuality a sin.
