The president of a national teachers union called the NRA's school-safety plan a "cruel hoax" that will lead to more gun violence rather than curbing active-shooter attacks.

The American Federation of Teachers' Randi Weingarten released a statement Tuesday responding to the NRA's school safety initiative that calls for arming teachers, among other measures, to better secure campuses.

"Today's NRA proposal is a cruel hoax that will fail to keep our children and schools safe," Weingarten said. "It is simply designed to assist gun manufacturers flood the nation and our schools with more guns and large magazine clips, which will simply lead to more violence."

Weingarten pointed to the Sandy Hook Elementary shooting , saying armed teachers wouldn't have stopped Adam Lanza's rampage. She said the NRA's proposal is meant to "distract the American people from the real, serious gun problem we face in America."

Weingarten also called for "bipartisan, commonsense gun safety legislation, including comprehensive background checks, and a ban on large magazine clips and military assault weapons."
