US crude oil production has increased by 90% under Obama. 2015 was the first year in memory that the US produced more oil than it imported. Over a third of the imported oil comes from Canada. Some also comes from Mexico and Columbia, both friendly countries. So most of our oil comes from friendly sources.
It should be noted that Citgo is a wholly owned subsidiary of the oil company that is owned by the Venezuelan government, which is run by anti-Semitic rashaim. Hopefully they will be overthrown soon as the country is now a failed state.
