ROUGH CUT (NO REPORTER NARRATION) STORY: President Barack Obama met with the National Security Council Tuesday where he is expected to be updated on the investgation into the attack in Orlando, Florida where 29-year-old gunman, Omar Mateen killed 49 people at a gay nightclub over the weekend. Authorities so far believe Mateen acted alone, without direction from the Islamist militant groups he voiced sympathy for, authorities said as they investigated the worst mass shooting in modern U.S. history. Federal law enforcement officials said the 29-year-old gunman, who worked as a private security guard at a gated retirement community, seemed to have been largely inspired by radical ideology he was exposed to over the internet. President Barack Obama on Monday called Mateen, a U.S. citizen born in New York to Afghan immigrant parents, an apparent example of "homegrown extremism."
