RICHMOND, Va. (AP) _ Virginia Gov. Terry McAuliffe is outlawing the open carry of guns in some state-owned building and pushing for tighter gun control measures. McAuliffe signed an executive order Thursday at the Capitol setting up a task force aimed at more robust prosecution of gun crimes. The order also establishes a statewide tip line to report gun crimes, and orders state police to request a trace of every gun involved in a crime in Virginia. U.S. Sen. Tim Kaine and Attorney General Mark Herring joined the governor, along with parents of victims killed in gun-related crimes. McAuliffe has been an outspoken advocate for tighter gun control measures, but has failed to get those efforts past the Republican-controlled General Assembly.
