The Rachel Maddow video below sums up some issues re: Russia and Pres. Trump's campaign staff. Of special interest is Secretary of State Rex Tillerson because Pres. Trump's appointment of Tiillerson just didn't make much sense, given that--
(1) Mr. Tillerson had no diplomatic or government experience.
(2) Mr. Trump reportedly had never really known Mr. Tillerson before the appointment.
Mr. Tillerson didn't even support Trump: Tillerson backed Jeb Bush instead in the Republican primaries, a fact that Mr. Trump probably isn't fond of.
As well as Mr. Tillerson, the video covers Erik Prince, Jared Kushner, and Carter Page--all of whom were tied to Mr. Trump's campaign and had unexplained meetings with Russian officials.
