The wife of the gunman who killed 49 people at an Orlando gay nightclub knew of his plans for the attack and could soon be charged in connection with the deadliest mass shooting in modern US history, a law enforcement source said on Tuesday. The source said that a federal grand jury had been convened and could charge Omar Mateen's wife, Noor Salman, as early as Wednesday. "It appears she had some knowledge of what was going on," said US Senator Angus King, a member of the Senate Intelligence Committee, which received a briefing on the attack on Tuesday. "She definitely is, I guess you would say, a person of interest right now and appears to be cooperating and can provide us with some important information," King told CNN. Mateen, who was shot dead by police after a three-hour standoff at the Pulse club early on Sunday, called 911 during his shooting spree to profess allegiance to various militant groups. Federal investigators have said he was likely self-radicalized and there was no evidence that he received any instructions or aid from outside groups such as Islamic State. Mateen, 29, was a US citizen, born in New York of Afghan immigrant parents. "He appears to have been an angry, disturbed, unstable young man who became radicalized," President Barack Obama said. Mateen, who was a security guard, was systematic during his rampage, working his way through the packed club shooting people who were already down. He apparently wanted to ensure they were dead, said Angel Colon, a wounded survivor. "I look over and he shoots the girl next to me and I was just there laying down and thinking: ‘I'm next, I'm dead,'" he said. Mateen shot him twice more, one bullet apparently aimed for Colon's head striking his hand, and another hitting his hip, Colon said at Orlando Regional Medical Center, where he is one of 27 survivors being treated. FoxNews.com, citing an FBI source, said prosecutors were seeking to charge Mateen's wife as an accessory to 49 counts of murder and 53 counts of attempted murder and failure to notify law enforcement about the pending attack and lying to federal agents. NBC News said Salman told federal agents she tried to talk her husband out of carrying out the attack. But she also told the FBI she once drove him to the Pulse nightclub because he wanted to scope it out, the network said. Salman's mother, Ekbal Zahi Salman, lives in a middle-class neighborhood of the suburban town of Rodeo, California. A neighbor said Noor Salman only visited her mother once after she married Mateen. Noor Salman's mother "didn't like him very much. He didn't allow her (Noor) to come here," said neighbor Rajinder Chahal. He said he had spoken to Noor Salman's mother after the Orlando attack. "She was crying, weeping." Obama denounced Donald Trump for his proposed ban on Muslims entering the United States, joining fellow Democrat Hillary Clinton in portraying the Republican presidential candidate as unfit for the White House. Since the shooting, Trump criticized Obama for not using the term "radical Islamic terrorism" to describe violent militants. "What exactly would using this label accomplish, what exactly would it change?" Obama replied. "Someone seriously thinks we don't know who we're fighting? ... There's no magic to the phrase ‘radical Islam.' It's a political talking point. It is not a strategy." — Reuters
