BOB CUSACK (EDITOR-IN-CHIEF, THE HILL): I think that [incoming national security adviser] John Bolton deserves his own team. And if they're McMaster holdouts or Obama holdouts, they're going to have to go. Because, in all likelihood, the leakers are probably from people who don't agree with the president. We saw that recently with the call to [Russian President Vladimir] Putin. That upset the president, understandably. Now, Bolton is no shrinking violet. So, at the same time, how is he going to work with chief of staff [John] Kelly? [Secretary of Defense] Jim Mattis reportedly concerned about working with Bolton. I think those -- he's dealing with some very big personalities here.
