A group of Senate Democrats released legislation on Monday that would mandate refunds of tariffs paid under President Donald Trump’s higher duties that the Supreme Court struck down on Friday.

The legislation, led by Sen. Ron Wyden of Oregon, Jeanne Shaheen of New Hampshire and Ed Markey of Massachusetts, follows the Supreme Court’s momentous 6-3 decision on Friday ruling against a majority of Trump’s tariffs.

“Trump’s illegal tax scheme has already done lasting damage to American families, small businesses and manufacturers who have been hammered by wave after wave of new Trump tariffs,” Wyden, the top Democrat on the Senate Finance Committee, said in a statement.

“Senate Democrats will continue fighting to rein in Donald Trump’s price-hiking trade and economic policies. A crucial first step is helping people who need it most, by putting money back in the pockets of small businesses and manufacturers as soon as possible,” he said.

The White House had no immediate comment on Monday.
