John Russell Houser fatally shot two women at the Grand Theatre in Lafayette last month (Jul15) before turning the gun on himself.

Following the tragedy, Schumer expressed her condolences on and subsequently vowed to use her celebrity status to advocate for gun control as fans reached out to her and urged her get involved in the debate.

She says, "I was, like, legit (sic) heartbroken just to get that news. I got a call and I had a lot of missed calls, so I assumed, like, there was a sex tape of me out or something, and I was kinda preparing for that... It was so horrible."

And when her cousin, U.S. Senator Chuck Schumer invited her to attend a press conference urging officials to introduce stricter gun laws in America on Monday (03Aug15), the actress/comic didn't hesitate to sign up.

She adds, "The second this happened, you wanna act. I wanted to go down there (Louisiana) and do whatever I could, so this has been in the works."

At the press conference, she told reporters she was a big fan of her relative's support of new legislation which will create financial incentives for states which comply with background check system records and punish those that do not.

She said, "Preventing dangerous people from getting guns is very possible. These are my first public comments on the issue of gun violence, but I promise they won't be my last."
