Members of Congress are attending emergency security briefings after the killing of a Minnesota state lawmaker. The shooting at the lawmaker’s home has raised fresh fears about the safety of members of Congress. The suspect in the Minnesota attack had dozens of federal lawmakers listed in his writings, in addition to the state lawmakers and others he allegedly targeted. The shootings come after credible threats to members of Congress have more than doubled in the last decade and after several violent attacks on lawmakers and their families. Connecticut Sen. Chris Murphy said lawmakers are “clearly at the point where we have to adjust the options available to us.”
