House Democrats are poised to pass new legislation this week that would raise the legal age of purchase for some semiautomatic rifles to 21, promote safe storage of firearms and ban the sale of large-capacity magazines. Those measures appear doomed in the Senate, where they would need the support of at least 10 Republicans to break a filibuster. On Monday, Texas Republican Senator John Cornyn said GOP senators needed at least another week to nail down a bipartisan deal on gun violence.

This comes amid a steady drumbeat of shootings across the United States. On Monday, Philadelphia District Attorney Larry Krasner said a weekend mass shooting began when two men licensed to carry firearms traded 17 shots on a street packed with innocent bystanders. Three people were killed, and 11 others were struck by bullets. Krasner called on lawmakers to take action on gun violence immediately.

Larry Krasner: “Any legislator who is not willing to put the lives of innocent bystanders, of women and children and young adults, above their political future belongs out of office. And I don’t care whether they’re Republican or Democrat.”
