Christie on gun violence: 'Lock up these violent criminals'
Christie again focused on his record as New Jersey governor when asked about how he'd address shootings and gun violence plaguing the nation.
He accused prosecutors of not arresting violent criminals and said a "President Christie" would appoint attorney general to instruct U.S. attorney to do so.
"We have plenty of room in the federal prisons to lock up these violent criminals and clean up what's going on all across this country and these individuals," Christie said.
