Police in Rhode Island say they have a person of interest in custody after a shooting at Brown University killed two students and wounded nine others.

The incident happened Saturday afternoon in a classroom during final exams.

The shooting paralyzed the campus, with students sheltering in place for hours. Nine students with gunshot wounds were taken to the hospital, with one in critical condition. An FBI agent says the arrest took place at a hotel in Coventry, about 20 miles (32 kilometers) from Providence.

Senate Democrat criticizes GOP leaders over gun policy

Connecticut Sen. Chris Murphy, one of the leading Democratic voices on gun policy, said Sunday that the prospects of new restrictions on firearms were “slim.”

“As we know right now, unfortunately, the Republicans in Congress don’t ever meaningfully break from this president,” Murphy said on CNN’s “State of the Union,” arguing that Trump and the GOP were too aligned with the gun lobby.

Murphy added: “That doesn’t mean I won’t try.”
