Prosecutors say the widow of the gunman who killed 49 people at a gay nightclub knew his plans. But the defense said Noor Salman was unaware of her husband Omar Mateen's intentions. Prosecutors believe she knew based on statements she gave to federal investigators. She told them, I wish I had ... told his family what he was going to do." Salman made that comment right after she said she was sorry for the shooting rampage. This was hours after the shooting occurred in 2016.
