I don't know. But I think it as to be something in context with Five eye-UK intel, because the last series of tweets about bad weather in the Midwest were clearly about MI6 and the fact that they are not really our friends. (MI6, that is, not the British people). It is just speculation but my instincts are that Trump has got something very incriminating about tampering with, blackmail,  or targeting  the Supreme Court.  If it involves foreign actors then the American culprits are guilty of espionage and treason and deserve to hang.
