Remember this, the AATIP (the Advanced Aerospace Threat Identification Program) didn't get close down, it simply quit accepting financing, notwithstanding, it is as yet getting subsidizing from the CIA and the Navy.

So the CIA/Navy/DoD is as yet investigating UFOs. This essentially implies Luis Elizondo, the previous Director of the AATIP answered to the DoD/CIA/and the Navy, the money pushers for AATIP. Elizondo said he was kept from detailing all that he needed to Secretary Mattis. We can finish up it is likely it was the CIA that needed to keep Mattis oblivious to some stuff.
