Comedian Amy Schumer and distant cousin Sen. Charles Schumer continued their push for gun control on the steps of City Hall on Sunday. Amy Schumer said gun violence hit home when she heard about a gunman opening fire at a screening of her movie Trainwreck in Lafayette, Louisiana this summer, killing two and injuring nine.

She urged people to back Sen. Schumer's bid for stricter gun purchase background checks, including mandatory background checks for online gun sales and at gun shows.

"If you're a violent criminal, a domestic violence offender or severely mentally ill, you will not be able to purchase a gun," the comedian said.

The two first teamed up on the pitch in August.

"Since [then], there have been at least 95 shootings across the country. We can't just sit back and continue to allow these mass shootings to become common place," Sen. Schumer said.

Citing the death of a 12-year-old girl hit in her Hempstead house by a stray bullet earlier this month and the fatal shooting of NYPD Officer Randolph Holder last week, Amy Schumer called the carnage "gut-wrenching." She called on people to voice their support on social media using the hashtag #AimForChange. Sen. Schumer wants to force a congressional vote on his proposal early next year.

The actor used her gig hosting Saturday Night Live earlier this month to take shots at gun-owning culture.
