"HOUSTON — The Obama administration on Friday gave oil companies temporary permission to export a limited amount of oil to Mexico at a time when a glut is cutting into domestic petroleum profits and employment.
The decision by the Commerce Department fell short of removing a ban on crude exports that goes back to the 1970s, when international oil boycotts produced long lines at gasoline stations and threatened the American economy. It also does not make a broad national security exception for Mexico, which has long existed for Canada, to release larger-scale exports.
But support for an end to the ban is growing in Congress among Republicans and Democrats from oil states like Texas. The administration has been reluctant to remove the ban, although it has already given permission over the last two years to American producers to sell some extra-light forms of crude, called condensates, on a limited basis."
