Jones Act waiver for tankers?

Anyone know why CBP is granting waivers for tankers?
Aren’t there any US flag ships that can do the job?

This news is a real stoke of bad news for the maritime industry; especially since the Jones Act has been under attack lately on many fronts. It’s easy to see that this could send the US maritime industry down a very slippery slope. Eventually this temporary fix will become more commonplace until it is accepted practice and not a dire straights/ last resort sort of thing. I myself would be interested in seeing the availability of US tankers to ship OUR oil.
