Senator Chris Murphy of Connecticut wrote an op-ed in Fox News calling for action on gun violence as he begins bipartisan negotiations with Republican senators.
Mr Murphy, who was sworn in weeks after the Sandy Hook shooting in Newtown, is the most outspoken Democratic senator when it comes to gun safety. Last week, after Salvador Ramos shot and killed 21 people in Uvalde, Texas, Mr Murphy gave a floor speech imploring the Senate to act.
