The Biden administration has temporarily lifted a century-old shipping rule for one company to ease petroleum shortages on the East Coast after a ransomware attack shuttered a major fuel pipeline, and gas prices rose to a seven-year high.

Homeland Security Secretary Alejandro Mayorkas said in a statement late Wednesday he had approved a “temporary and targeted waiver” to one company seeking to transport fuel from the Gulf Coast to the Eastern Seaboard. The 101-year-old Jones Act requires goods carried between U.S. ports to be transported on ships built, owned, and operated by Americans.
