A pair of Republican Louisiana senators said Wednesday they received assurances from President Trump that he would not grant waivers to bypass the Jones Act, a century-old law regulating domestic maritime commerce, to ease the transport of natural gas to the Northeast and Puerto Rico.

The office of Sen. Bill Cassidy said he and other members of Congress met with Trump earlier Wednesday at the White House “to advocate on behalf Louisiana shipbuilders and maritime workers,” and secured “a commitment from the president to not go forward with the proposed waivers.”
