I love all these headlines that Trump is furious someone leaked that he congratulated Putin, even though the memos said not to, in ALL CAPS.
Duh! VSG* Trump Leaked This!!!
Look, for his supporters, it paints him as a rebel - which he loves. It creates chaos in the West Wing - which he admits he loves. And it gives him a chance to fire someone later and suggest (without actually saying it) that the fire-e was the leaker.
It doesn't take a rocket scientist...
