Five Republican Senators filed an amicus brief on Dec. 15 with the U.S. Supreme Court, urging it to take up a case over the limits of the president's authority under the Section 232 national security tariff statute. The brief, signed by Sens. Pat Toomey, R-Pa.; Mike Crapo, R-Idaho; Bill Cassidy, R-La.; Mike Lee, R-Utah; and Ben Sasse, R-Neb., argues against a U.S. Court of Appeals for the Federal Circuit opinion spurning time limits imposed in the statute. The time limits are crucial to ensuring that "Congress makes the major policy decisions regarding the regulation of foreign commerce," the lawmakers said.
