Mir Seddique is the father of Omar Mateen of Port St. Lucie, Florida. Seddique told NBC News that his son got angry when he saw two men kissing in Miami a couple of months ago and thinks that may be related to the shooting.
Seddique says: "We are saying we are apologizing for the whole incident. ... We are in shock like the whole country."
