  • The shooter is among the dead, Orlando Police Chief John Mina confirmed at a press conference.

  • Orlando Mayor Buddy Dyer says the shooter used an assault rifle on all of the victims. A handgun was also found on the scene.
  • Law enforcement officials are investigating whether the shooting was related to terrorism, the AP reports. A report from the Daily Beast says that the shooter had been "a known quantity" to the FBI, according to an FBI source who said the shooter had been identified as a "person of interest" in 2013 and 2014. Congressman Adam Schiff told CNN's Jake Tapper that Mateen "pledged allegiance" to ISIS at some point during the incident.
  • The shooter had training as a private security officer, according to multiple media reports.
  • The father of the shooter told NBC News that the shooting "has nothing to do with religion," but said that his son became angry after recently seeing two men kiss, an incident that he believes may be connected to the shooting.
