Gun rights supporters are gathering at state capitols across the U.S. today, pushing back against a wave of student-led gun violence protests that some see as a threat to the Second Amendment.

A group called the National Constitutional Coalition of Patriotic Americans organized the Saturday rallies, gaining permits to gather outside most U.S. statehouses, said David Clayton, of West Virginia, one of the coalition's founders.

The rallies come less than three weeks after hundreds of thousands marched in Washington, New York and other U.S. cities to demand tougher gun laws after the February school shooting that killed 17 in Parkland, Florida.
