I wonder how long this deal has actually been in the works, and Trump, seemingly privy to this knowledge, saw a good opportunity to take credit by pre-empting the inevitable announcement of a sell off. Why else would he announce his plans of an executive order instead of just doing it?
you might be right, but there are other reason to announce instead of doing: getting leverage, getting attention, being someone that talks a lot and does much less, not having a brain/mouth filter... probably a mix of trying to get leverage for something probably unrelated and getting some attention (possibly diverting it from something else)
