US is actually really good at processing that type of crude. Much better than the oil we drill domestically. Don't forget that US oil companies used to dominate Venezuela. In 1976, Venezuela bought out the companies and paid them what they claimed they were worth on their financial/tax ledgers. Ofc all the companies massively deflated their worth to avoid taxes so this angered them and they've never really stopped complaining about it.

Trump has basically enacted their revenge for that.
