Amy Schumer's Funniest Joke Yet...

Amy Schumer, calling herself "heartbroken" after a gunman killed two people watching her movie in Louisiana, joined her senator cousin on Monday to call for a stronger background-check system for gun buyers.

"These shootings have got to stop," she said. "I don't know how else to say it."

The comedian and Sen. Charles Schumer, a New York Democrat who is her second cousin once removed, announced a bill to reward states that submit records on felons, spousal abusers and the mentally ill to the federal background check system. It would penalize states that don't.

They also want the Justice Department to survey states and find out which have the best standards for involuntary commitment to mental health facilities, and they want Congress to restore proposed cuts to mental health programs.

"These are not extreme ideas," Amy Schumer said. "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."
