Republican and Democratic U.S. senators plan to introduce as soon as Tuesday legislation that would force President Donald Trump to obtain Congress' approval before imposing tariffs on national security grounds, a senior senator said on Tuesday.
Republican Sen. Bob Corker, chairman of the Foreign Relations Committee, said legislation would be introduced on Tuesday or Wednesday that would pare back the president's authority under Section 232 of the Trade Expansion Act of 1962.
Prompting criticism from many of his fellow Republicans as well as business groups, Trump decided last month to open a trade investigation into whether auto imports had damaged the U.S. auto industry, which could lead to tariffs of up to 25 percent on "national security grounds."
