But Toomey hopes the Senate will — again — consider his bill to expand background checks to Internet sales and gun shows. It’s twice failed, including after the Sandy Hook massacre.

“It’s hard to believe that it’s still the state of the law that terrorists can get guns,” Casey said.

But Casey raises concerns about President Trump’s budget proposal, which he says slashes millions of dollars from programs designed to address mental health issues and help prevent school violence.
