One picture that explains the remarkable White House staff turnover, by Chris Cillizza.

The photo above was taken on January 28 in the Oval Office.
President Donald Trump was in the midst of an hour-long “congratulatory” call with Russian President Vladimir Putin, according to the White House’s readout. In the photo, he is surrounded by his White House brain trust: chief of staff Reince Priebus, chief strategist Steve Bannon, press secretary Sean Spicer and national security adviser Michael Flynn. (Vice President Mike Pence is also there!)
