Trump uses Florida shooting to criticize Obama

President Barack Obama decried the deadliest mass shooting in American history on Sunday as an "act of terror" and an "act of hate" targeting a place of "solidarity and empowerment" for gays and lesbians. He urged Americans to decide whether this is the kind of "country we want to be."

Speaking hours after the shooting at a gay nightclub in Orlando, Obama said the FBI would investigate the shooting as terrorism but that the alleged shooter's motivations were unclear. He said the U.S. "must spare no effort" to determine whether the suspect, identified by authorities as Omar Mateen, had any ties to extremist groups.

"What is clear is he was a person filled with hatred," Obama said of the alleged shooter.

Donald Trump,  tweeted as President Obama began speaking: "Is President Obama going to finally mention the words radical Islamic terrorism? If he doesn't he should immediately resign in disgrace!"

Minutes later he added after a heavily armed man who said he was heading to a gay pride parade in Los Angeles was arrested early on Sunday: "Reporting that Orlando killer shouted "Allah hu Akbar!" as he slaughtered clubgoers. 2nd man arrested in LA with rifles near Gay parade."
