Good Saturday morning. Situational awareness: Mueller has told the White House that he'll probably seek to interview six current and former White House aides: Hope Hicks; Sean Spicer; Reince Priebus; White House counsel Don McGahn; one of his deputies, James Turnham; and Josh Raffel, a White House spokesman who works closely with Jared Kushner.

Be smart: These six know a lot about the process of the West Wing, and saw and heard a lot that Mueller's interested in. This is another clue that Mueller is obsessed with understanding how things worked, building his web of details and connections — and methodically working from the outside of the circle to the very center of it.
