Amy Schumer joined her cousin, Sen. Chuck Schumer (D.-NY), at a Manhattan press conference on Monday to help him announce a new plan and public push to crack down on mass shootings and gun violence in America.

The two came together in the wake of last month's shooting at a movie theater in Lafayette, Louisiana, which occurred during a showing of Amy Schumer's comedy "Trainwreck." The shooter, who was identified as a "drifter" with a history of mental health issues, killed two women, Mayci Breaux and Jillian Johnson, and injured nine others.

"I'm not sure why this man chose my movie to end those two lives and injure nine others, but it was very personal for me," said Amy Schumer on Monday. "We always find out how the shooter got their gun and it's always something that never should have happened in the first place."

Sen. Schumer then thanked her for joining him in the push for strengthening gun control laws, saying, "I have a lot of press conferences but I almost never get this much attention."

The room was packed full of reporters.

The Schumers then proposed three key actions, which were laid out in a pre-conference press release, meant to combat gun violence.

First, Sen. Schumer unveiled new legislation that will reportedly financially reward states that "submit all necessary records into the background check system and creates penalties for states that do not submit all records," his office said.

The pair then called on the Department of Justice to write a report "comparing all states’ standards for involuntary mental health commitment," and urged it to give "federal recommendations" for best practices.

Finally, the duo called on Congress to fund mental health and substance abuse programs that provide treatment to those who need it most. They also urged increased funding for the Substance Abuse and Mental Health Services Administration.

Speaking during the briefing, Sen. Schumer listed out several high-profile mass shootings that have rocked the nation in recent weeks, including a racially motivated attack on a historic church in Charleston that left 9 people dead. Shortly after the shooting, the FBI revealed that the shooter, Dylann Roof, was able to purchase a gun because of a flawed background check system.

"If there's anything that the mass shootings...have taught us, it's that we should do everything in our power to close these loopholes," said Sen. Schumer. "We all know that if laws were tighter, the shooter in Charleston would not have been able to purchase a gun."

"We need a background check system without holes and fatal flaws. We need one with accurate information that protects us like a firewall should," added Amy. "The critics scoff and say, ‘there is no way to stop crazy people from doing crazy things.’ They’re wrong. What Chuck is describing are sensible measures and restrictions. No one wants to live in a country where a felon, the mentally ill, or other dangerous people can get their hands on a gun with such ease. The time is now for the American people to rally for these changes.”

Amy, a comedian who stars in Comedy Central's "Inside Amy Schumer," tweeted in the wake of the shooting that her heart was broken when she heard the news.

A fan of Amy's, Sarah Clements — who is also the daughter of a Sandy Hook shooting survivor — then wrote the comedian an open letter asking she take a stand against gun violence.

"Don't worry I'm on it," Amy then responded on Twitter. "You'll see."

Schumer, the senator, has sponsored various pieces of of legislation related to gun control, ranging from gun buyback programs to anti-gun trafficking laws.

He's also sought to close loopholes related to the purchasing of guns over the Internet and by juveniles. He has an "F" rating by the National Rifle Association — a point he's frequently touted.
