A bill to bolster the national background check system used for gun purchases crossed a critical milestone this week, getting enough support to break a filibuster and pass the Senate.
The legislation reinforces existing laws by ensuring that authorities report criminal records to the system and penalizing agencies that don't.
The effort has been championed after multiple mass shootings where the alleged gunmen were able to purchase firearms despite past charges or warnings about their behavior.
“I can't tell you how disappointed I am that the United States Senate has done nothing, nothing, to prevent [mass shootings] from happening in the future. We're close to 60 bipartisan co-sponsors," he said from the Senate floor.
