While investigators try to piece together what led the Orlando gunman to carry out an unspeakable act of terror, the attack is upending the 2016 campaign debate as the two presumptive rivals go toe-to-toe on terror with two very different messages. 

In back-to-back speeches Monday, Donald Trump doubled down on his call for a Muslim immigration ban while decrying what he described as a “deadly ignorance” that is hurting the country — and Hillary Clinton renewed her call for an assault-weapons ban while vowing to stop “lone wolf” terrorists. 

Trump, speaking in New Hampshire, focused largely on his plans for an immigration crackdown. Trump said he wants to “suspend immigration from areas of the world where there is a proven history of terrorism” against the U.S. or its allies.
