Retired Air Force Lt. Col. Donald Arias said on Monday that the families who lost loved ones in Friday's shooting at Naval Air Station Pensacola in Florida deserve full disclosure about what happened.

“Prior to this administration, we lived through eight years of political correctness, where they got rid of all references to Islamic terror in training materials for the FBI, etc.,” Arias, whose brother died at the World Trade Center on Sept. 11, 2001, told “Fox & Friends.” 

“It’s time we put that back in there. It’s also time that the Saudi prince comes forward and – you know, he says he’s sorry, he says he’s angry, he says he loves America – that’s not enough.”

“If he really loves America and he really means that, he needs to give full disclosure to these families about who these foreign nationals were.”

Investigators said Sunday they're working under the presumption the shooting was an act of terrorism involving a lone gunman. All foreign students at the base are accounted for and no arrests have been made in connection with the attack.
