The White House has vowed not to give up the tariffs and will consider other options in addition to appealing

Mr. Trump's enthusiasm for new tariffs has not diminished in spite of the worst blow yet to his signature tariff policies. White House officials were quick on Thursday to say that if his appeal failed, Mr. Trump would press ahead with the same tariffs through other legal powers. At the same time, the administration is also actively trying to overturn the court's decision, saying it will take the case to the Supreme Court as early as Friday if a federal appeals court does not overturn the original ruling. The White House said on Thursday that it was evaluating other options, but advisers acknowledged they could take longer.
