Not necessarily, but I do think that if there's a big UFO coverup dating back half a century, it's obviously highly compartmentalized, and probably more tightly controlled than your run-of-the-mill top secret (or even SCI) documents. Trump's a clown, it's obvious he's a clown, and the people who control such a hypothetical UFO program would do everything in their power to prevent such a clown from 1) becoming aware of their program, and if necessary 2) gaining access to information about their program.
