The FBI has confirmed that suspected Orlando shooter Omar Mateen had been investigated by the department twice in the past for suspicious activity. 

The FBI revealed at a press conference today that it first became aware of Mateen in 2013, after he made inflammatory comments to coworkers alleging possible terrorist ties; and again in 2014, for possible ties to American suicide bomber Moner Mohammad Abu-Salha.

But both cases were closed after the claims either could not be verified or didn't merit further investigation.

Former FBI Assistant Director weighed in on Justice, telling Judge Jeanine Pirro that the agency has more targets than they do resources.

He said the rules of engagement need to be changed, saying that Mateen, having been on the FBI's radar, should never have been able to buy a gun or get a security job without the FBI knowing about it.

"They don't clear him...and why there's not traps left everywhere for this guy on watchlists, on gun lists. How can he work for a security company? These things are crazy."
