The vote came after the Senate rejected three GOP amendments, including one that would have limited the Trade Adjustment Assistance (TAA) program to workers who lose their jobs due to a specific increase in imports from a country with which the U.S. has a free trade agreement. Another would have required a report on the consequences of failing to act on pending trade deals, and another would have required the U.S. to sell Taiwan new F-16 fighter planes.
