Amy Schumer is lending her voice to a new, more serious cause, joining her cousin, U.S. Sen. Chuck Schumer (D-N.Y.) in a push for laws that crack down on gun violence.

During a press conference in New York on Monday, the Trainwreck star and writer made an emotional plea for reform that introduced a new plan for gun control. Her stand comes about two weeks after a man opened fired during a screening of her new movie in Lafayette, Louisiana where two women were killed.

"We're here today to say 'enough is enough' to mass shootings in our schools, our college campuses, our military bases and even our movie theaters," she said. "These shootings have got to stop. I don't know how else to say it."

Schumer added, "this man shouldn't have been able to put his hands on a gun in the first place."

Schumer said the legislation "deserves unanimous support...The critics scoff and say, 'There's no way to stop crazy people from doing crazy things,' but they're wrong. These are not extreme ideas.

"These are my first public comments on gun violence," she added. "But I can promise you, they won't be my last."
