The tariffs U.S. President Donald Trump imposed last week on scores of countries are likely to stay in place rather than be cut as part of continuing negotiations, Trade Representative Jamieson Greer said on Sunday.

The president typically ties his tariffs to trade policy, but he hit Brazilian products with the highest rate of any country's goods largely due to politics.

On Thursday, Donald Trump announced sweeping new tariffs against U.S. trading partners that will go into effect next week. The announcement came on the same day that an appeals court grappled with the question of whether Trump’s tariffs are even legal.
