[Update 12:30 p.m.] Officials have now increased the death total from this morning's Orlando shooting to 50 people, making it the deadliest mass shooting in U.S. history, and the deadliest attack against the LGBTQ community in U.S. history. Police initially thought around 20 people had been killed. 53 more people have been hospitalized as well.

"All of the killing that was done was done with a single assault rifle," said Orlando Police Chief John Mina. He also identified the gunman as Omar Mateen, a U.S. citizen living in Port St. Lucie who was born in America and whose family is from Afghanistan. Mina added that Mateen used an AR-15 rifle in the attack, the same gun used at Sandy Hook and San Bernadino.

After calls from Orlando Mayor Buddy Dyer, Gov. Rick Scott has now declared a state of emergency for Florida in the wake of the attack.
