The deadliest mass shooting in U.S. history prompted calls on Sunday by some members of Congress for legislation to tighten control of weapons sales, although there are slim hopes for much change after 50 people were killed at a Florida nightclub.
Democratic Sen. Robert Casey said he would announce a bill on Monday that would ban anyone convicted of a misdemeanor hate crime from owning a firearm.
Under current law, those with felony convictions are prohibited from buying or possessing a gun, but those convicted of misdemeanor hate crimes are not. Casey's bill is called the "Hate Crimes Prevention Act."
