(MCT) — WASHINGTON — A day after President Barack Obama announced a wide-ranging series of gun-control initiatives, the administration kicked off its campaign to create public support and pressure lawmakers to pass the most comprehensive legislation since the mid-1990s.

“We’re going to take this fight to the halls of Congress. We’re going to take it beyond that,” Vice President Joe Biden told the U.S. Conference of Mayors Thursday. “We’re going to take it to the American people. We’re going to go around the country making our case, and we’re going to let the voice of the American people be heard.”
