Okay, this has (according to the AP article been 'going on for up to six years'. Perry has been Energy Secretary since March of 2017. Now, by my meager calculations, that means (within the 6 year bounds of the 'up to'), that more of this has been going on under Obama's watch, and that it was already happening when Perry took the position.
It was discovered while Perry was Sec. of Energy, so who found it out?
