ROUGH CUT (NO REPORTER NARRATION) A surgeon treating victims of the attack at an Orlando nightclub that killed 50 people and injured 53 more appealed for blood donations at a news briefing on Sunday (June 12). Dr. Michael Cheatam said Orlando Regional Medical Center had called in six trauma surgeons, including a pediatric surgeon, to handle the flood of victims. A gunman killed 50 people and injured 53 in a crowded gay nightclub early on Sunday before being shot dead by police, authorities said, in what appeared the deadliest mass shooting in American history. The shooter was identified as Omar S. Mateen, a man that a senior FBI official said might have had leanings towards Islamic State militants. Officials described the attack as a "terrorism incident" though cautioned that the suspected Islamist connection required further investigation. The death toll given by Orlando Mayor Buddy Dyer and police to reporters made the attack the deadliest single shooting incident in U.S. history, eclipsing the 2007 massacre at Virginia Tech university, which left 32 dead. The FBI said it was still trying to pin down whether the mass shooting was a hate crime against gays or a terrorist act. President Barack Obama ordered the federal government to provide any assistance needed to Florida police investigating the shooting, the White House said in a statement.
