The oil connections

I've been thinking about Exxon, Rex Tillerson, and Russian oil companies.  I think they've been in the propaganda game for a long time.  I wonder if Rex was working with Putin on climate change denial and when Exxon started getting under pressure from the government, Rex saw that a move towards government control was the best way to solve his problems.  I wonder if they used the same propaganda machines they built when they were trying to convince the world that climate change isn't real.
