Ok according to that article in 2020, the DoE wanted to fill up the SPR (strategic petroleum reserve)...which if my calculations are correct, was already ~90% full at the time.
Interestingly enough, a few years prior to ^that, trump wanted to sell off half of the SPR over a 10 year period... Conservative think tank, The Heritage Foundation, took it a step further and wanted to deplete the entire SPR.... Yes. The entire thing.
