U.S. Trade Representative Jamieson Greer said in an interview set to air Sunday that President Trump’s newly announced tariff rates are “pretty much set” and the public should not expect them to come down in the near future.

The tariffs U.S. President Donald Trump imposed last week on dozens of countries are expected to remain in effect rather than be reduced during ongoing trade negotiations, U.S. Trade Representative Jamieson Greer said Sunday.
