New York Daily News in their article, "FBI spied on Orlando gay club terrorist Omar Mateen for 10 months in 2013: FBI Director James Comey," would admit (emphasis added):
Mateen first appeared on authorities' radar in 2013 after the security guard's colleagues alerted the FBI to inflammatory statements he made to colleagues claiming "family connections to Al Qaeda," according to Comey.
Mateen also told coworkers he had a family member who belonged to Hezbollah, a Shia network that is a bitter enemy of ISIS — the network he pledged allegiance to the night of the carnage, Comey noted.
The FBI's Miami office opened an inquiry into Mateen.
"He said he hoped that law enforcement would raid his apartment and assault his wife and child so he could martyr himself," Comey said.
Nevertheless, FBI investigators investigated Mateen, who was born in New York, for 10 months. They introduced him to confidential informants, spied on his communications and followed him. They also interviewed him twice.
