Only sometimes is blackmail needed, but they have it on most of them.
I would agree. But in President Trump’s administration, if the enemedia has a blackmail card on someone, it must be used only in an extreme situation, and after that it becomes pretty worthless. As others have pointed out, not only is President Trump smoking out the leakers, he is finding out who they gave the information to, and THAT might result is the successful prosecution of members of the enemedia!
