Donald Trump can do whatever he wants because he says so. He has the "absolute right" to spill the beans about, well, anything really, if he feels like it. Who cares that some intelligence operative somewhere who was supplying us with lifesaving information will now dry up and maybe be killed for his or her good deeds.
But all those other people—like Hillary—they were "crooked" and "un-American" leakers who "mishandled classified info," which is a "big problem" and they "must apologize" and be “charged.”
Because Donald Trump says so!
