In the wake of the journalist slayings near Roanoke, Va., White House Press Secretary Josh Earnest said similar acts of violence could be prevented if Congress would enact “common sense” changes in gun control legislation. “Until we see a sufficient number of people in this country stand up and make clear that this is something that they’re going to insist members of Congress act on, we’re probably not going to see the kind of common-sense changes that we believe should be put in place,” Earnest said.
