"The implication that the bogus memo is being kept secret is also bogus. President Trump could order declassification of the memo at any time. But sharing new information about the investigation of Trump’s dealings with the Russians is not the goal here. The aim is to create the conditions in which Trump can fire Mueller."
I had forgotten the Pres can declassify. This might explain why Donnie hasn't been tweeting (as far as I know) to release the memo. If Donnie wanted it released he could do so easily.
