In the two years since a gunman killed 20 children and six teachers in Newtown, Ct., there have been at least 95 U.S. school shootings, including 23 in which at least one person was killed, say two groups calling on political leaders to take action against gun violence. USA Today says Everytown for Gun Safety and the affiliated Moms Demand Action for Gun Sense in America tracked news reports for every instance of a firearm discharged inside a school building or on school or campus grounds.

The groups will hold a 10 a.m. news conference at the U.S. Capitol by both of Connecticut’s senators, Democrats Richard Blumenthal and Chris Murphy; by U.S. Rep. Mike Thompson (D-CA), who chairs the U.S. House’s Gun Violence Prevention Task Force, and by Pamela Wright, whose son, Tyrone Lawson, 17, was shot and killed in Chicago last year after a high school basketball game.
