Breitbart.com's John Nolte attacked actress and comedian Amy Schumer's recent call for gun safety measures, claiming that the Trainwreck star doesn't actually care about a mass shooting that occurred during a screening of her film, but rather that she hoped to cynically use the shooting as “a great opportunity” to advance her career.

Two women were killed and nine other people were injured after a gunman opened fire during a screening of Trainwreck at a movie theater in Lafayette, Louisiana on July 23. The gunman, who had a history of domestic violence and bizarre behavior, committed suicide.

Following up on her pledge to engage on the issue of gun violence following the shooting, Schumer appeared alongside her cousin, Sen. Chuck Schumer (D-NY), at a press conference to promote new legislation to ensure that disqualifying records are submitted by states into the National Instant Criminal Background Check System. The bill includes other measures to address substance abuse and mental health issues.

During the Aug. 3 press conference, Amy Schumer said, “We're here today to say is enough is enough. To mass shootings in our schools, our college campuses, our military bases, and even in our movie theaters. These shootings have got to stop.” She continued, “For me, the pain I share with so many other Americans on the issue of gun violence was made extremely personal to me on Thursday, July 23 when ... 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.”

A visibly emotional Schumer concluded her remarks by saying, “These are my first public comments on the issue of gun violence, but I can promise you they will not be my last.”

On the Aug. 3 broadcast of the National Rifle Association's radio show Cam & Company, Breitbart News editor-at-large John Nolte attacked Schumer's motives, claiming that she did not care about the shooting but rather wished to use the tragedy to advance her career.

According to Nolte, Schumer sees the mass shooting as “a great opportunity, this occurred at my movie and now the focus is on me, and what can I do to enhance my career.”

“If she had any moral courage and she actually cared about what happened she would come out and she would say, 'Listen putting a sign on a movie theater that says no one inside it is armed, that this is a gun-free zone, is stupid.' She has the power to do this. She could make jokes about how stupid these gun-free zones are,” Nolte continued.

Instead, Schumer “is dressing up like she is a grown-up and she's just exploiting the situation because it's an opportunity for her to maybe increase her box office over the weekend,” he said, calling her advocacy  “cowardly.”

Nolte continued to claim that Schumer was using the shooting to advance her career, saying, “She's not thinking, she's just trying to please the right people to enhance her career. And she also -- there is a lot Oscar talk around her movie and that probably has something to do with it, too. You go the Angelina Jolie route so everybody suddenly starts to take you seriously.” Nolte said all he sees “is cynicism behind” Schumer's call for action.

Cam & Company host Cam Edwards said that he disagreed with Nolte's assessment and would not impugn Schumer with a cynical motive for her comments on gun violence. Nolte responded, “You're a nicer guy than I am, but I just see these unthinking Hollywood types and it just enrages me.”
