Sure he is. He’s simultaneously putting public pressure on weak sauce Comey via twitter to clean out the rats in his own agency while he finds his replacement, signalling DOJ to follow suit on prosecutorial procedures on leakers, and notifying the rest of FEDGOV to get clean or else...and he doesn’t need the media’s help or permission.
Agree! Comey may have an elaborate song and dance routine he goes through in private, to explain why it ‘takes time,’ to find the leaker/s. When Comey sees an ultimatum in public, however, he’s either going to miraculously find the leaker with lightning speed, or start cleaning out his desk.
Win/win.
