Rave reviews continue to come in for the new White House national security advisor, Lt. Gen. H.R. McMaster, including from frequent Trump administration critic John McCain (more on him below).

Perhaps the only people in Washington with any skepticism about the selection were Mike Flynn loyalists on the national security council staff—understandably so, for those who were brought in to work for the man McMaster is replacing. The caution is also understandable since McMaster’s been given “100 percent” control of hiring and firing, according to press secretary Sean Spicer. “The president’s been very, very clear with that. He is the national security advisor, and he will have whatever he needs to implement a successful team,” Spicer said Tuesday afternoon.
