The wife of the Orlando Islamic terrorist knew about the planned attack on the Pulse nightclub and failed to report the information to authorities according to NBC News:
Omar Mateen's current wife, Noor, told the FBI she was with him when he bought ammunition and a holster, several officials familiar with the case said. She told the FBI that she once drove him to the gay nightclub, Pulse, because he wanted to scope it out.
