House Democrats introduced legislation Friday designed to keep firearms from the hands of the severely mentally ill.

Sponsored by Reps. Mike Thompson (D-Calif.) and Ed Perlmutter (D-Colo.), the measure would expand the list of people prohibited from buying or possessing guns to include a broader swath of mental health patients and convicted criminals.

Supporters of the proposal say it’s a common-sense way to keep guns away from potentially dangerous people without encroaching on Second Amendment rights.
