I might be wrong on this but didn't Clinton bar the drilling of that shale in CO and UT?
I don't know about shale oil in Colorado or Utah.
BUT
The Lippo Group, James Riady and etc owned one of the two largest reserves of low- sulfur coal in the world.
After receiving campaign contributions directly or indirectly from Lippo etc, then President Bill Clinton by Presidential Directive created The Grand Staircase-Escalante National Monument.
The Grand Staircase-Escalante National Monument in Utah contained the other largest reserve of low- sulfur coal in the world.
The Utah Geological Survey valued all energy and mineral resources within the Monument at between $223 billion and $331 billion. (1997 Dollars)
Thus by creating the Monument, Clinton removed the completion for low- sulfur coal from The Lippo, James Riady etc, low- sulfur coal holdings.
Just a small part of The Clinton Legacy you and I are still paying for today.
