Floyd Lee Corkins II, the man who opened fire at the Family Research Council headquarters in August 2012, has pleaded guilty to three felony charges, including a terrorism offense, Christianity Today reports. According to a press statement from the U.S. Department of Justice, "Corkins ... pled guilty in the U.S. District Court for the District of Columbia to charges of committing an act of terrorism while armed, assault with intent to kill while armed, and interstate transportation of a firearm and ammunition." He will be sentenced on April 29. It is the first time anyone has been convicted of committing an act of terrorism with "intent to 'intimidate or coerce a significant portion of the civilian population of the District of Columbia or the United States.'" The DOJ also reported that Corkins specifically targeted the FRC in his attack, consulting a Southern Poverty Law Center list of organizations that oppose homosexuality.
