President Donald Trump on Wednesday informed seven more nations about new tariffs, singling out Brazil with a 50% duty because of what he called the "disgrace" of how former President Jair Bolsonaro has been treated.

Trump confirmed the U.S. will start delivering letters on Monday, detailing tariff rates and any agreements reached with various trading partners.

Trump threatens to impose tariffs of 25-40 percent from August 1 unless countries make concessions on trade.
