SAM typical stands for Special Air Mission, and this aircraft left out of Denver and Centennial Airport. i wonder whos aboard https://globe.adsbexchange.com/?icao=ae6961
You'll see SAM flights on a regular basis all over the world, there is no easy way to say who is aboard other than follow news reports from the area. Passengers could include military brass, state department trips, congressional trips, white house staff/advisors/cabinet members, among others. There is nothing mysterious about these flights, just high level gov't officials on official travel.
