A man who planned a mass shooting at a conservative Christian lobbying group's Washington headquarters in 2012 has been sentenced to 25 years in prison for the failed plot.

Floyd Corkins II was sentenced Thursday. Prosecutors had asked that he spend 45 years in prison. But Corkins' lawyer said his client was mentally ill when he entered the Family Research Council building and shot and injured a security guard. He says an 11 1/2 year sentence was appropriate.

Corkins was carrying 15 Chick-fil-A sandwiches during the shooting. He said he planned to smear them in his victims' faces as a political statement.

Chick-fil-A was making headlines at the time because of its president's opposition to gay marriage. The Family Research Council also opposes gay marriage.
