Comedian Amy Schumer wants you to help put an end to gun violence: she's asking the public to speak out on social media and lawmakers to support better background checks.

Schumer and her cousin Sen. Chuck Schumer (D-N.Y.) continued their fight against gun violence during a Sunday press conference on the steps outside New York City Hall.

"The stories [about gun violence] are gut-wrenching," Amy Schumer stated at the press conference. "A little boy last week was killed by his baby brother while playing cops and robbers. An NYPD officer was shot with an illegal gun by a chronic criminal."

"Schumer and Schumer," as they've begun referring to themselves, called upon lawmakers to support Sen. Schumer's proposed gun control bill that would enforce background checks to purchase guns online and at gun shows, improve the background check system as a whole, and prevent weapon trafficking across state lines, according to the AP.

The two asked everyone to share the hashtag #AimingForChange to encourage stronger gun laws and to use their own social media platforms to protect others against gun violence.

The pair started working together on this issue over the summer after a man opened fire during a showing of Amy Schumer's film, "Trainwreck" in Lafayette, Louisiana, killing two people. These deaths have haunted Schumer, who refused to name the shooter during an August press conference.

"On Thursday, July 23rd, a man sat down for my movie, 'Trainwreck,'" she said on Sunday. "I don't know why he picked my movie. It is something I live with every day."

During her Sunday appearance, Amy Schumer embraced Sarah Clements, the daughter of a survivor of the 2012 mass shooting at Sandy Hook Elementary School:

The cousins also shared an image calling for an end to gun violence on social media:

"#aimingforchange use this hashtag please write your congress people," Amy Schumer wrote. "We need a public outcry. There have been 100 shootings since Lafayette."

This comes two months after Schumer and Schumer held a press conference in New York to highlight the damage of gun violence in America:

"Preventing dangerous people from getting guns is very possible,” Amy Schumer told reporters at the time. "These are my first public comments on the issue of gun violence, but I promise you they will not be my last... I’m expecting a backlash and I’ll handle it."

She added that the problem of gun violence really hit close to home for her after two people were killed at a showing of her movie.

"These shootings have got to stop," Schumer said. "For me, the pain I share with so many other Americans on the issue of gun violence was made extremely personal to me on July 23 when ... I'm not even going to say his name ... He sat down for my movie 'Trainwreck' at The Grand Theater in Lafayette, Louisiana. Two lives were tragically lost and others injured. And I've thought about these victims each day since the tragedy."
