The anti-gun walkout protest is being pushed and funded by Michael Bloomberg’s Everytown for Gun Safety, which spawned the Students Demand Action group that participated on Friday

A small group of mostly high school students gathered in front of the White House on Friday as part of the National School Walkout, an anti-gun protest launched by a Connecticut teen following the shooting deaths of 17 people at a Florida high school in February.

Following a moment of silence plus 13 seconds to honor the 13 people shot and killed at Columbine High School on April 20, 1999, the group walked to the Capitol where speakers lashed out at Republicans and the National Rifle Association (NRA).

The organizers from schools in the D.C., Virginia, and Maryland region collected letters demanding gun control from protesters addressed to legislators and registered voters via text.
