ST. PAUL, Minn. (AP) — A group of high school students briefly shut down a Minnesota Senate committee hearing by calling on lawmakers address gun violence in schools.

School of Environmental Studies senior Josh Groven attended the Monday hearing on an unrelated bill and demanded the Senate Judiciary Committee hear bills that would restrict Minnesota's gun laws. Committee Chairman Sen. Warren Limmer briefly paused the hearing while security escorted Groven and others out.

Groven was one of nearly 20 students who earlier staged a sit-in protest at Limmer's office to call for expanded background checks on gun sales and other measures. Limmer met with the group when he returned to his office from a meeting. He says party leaders are considering the students' request.
