Truman was the one who started the CIA, FBI, NSA and all 18 intelligence agencies by signing the National Security Act in July 1947 -- just a few weeks after the Roswell crash.

And the UFO didn't actually crash in Roswell. It crashed just outside of CORONA. Look up Project Corona.

And the official cover story for Roswell. Project Mogul. President Trump's secret service name is MOGUL.
