Go ahead and push Brazil into the wafting arms of their fellow BRICS

Just lashing out indiscriminately and ineffectively to try to make it sound like he's doing something semi-useful apart from golfing, planning his stupid ballroom and arch, and rage-tweeting all hours of the night.

But didn’t the Supreme Court rule Trump’s previous tariffs exceeded the powers given to the president by Congress under a 1977 law providing him the authority to regulate commerce during national emergencies created by foreign threats?

Now the article didn't mention just what those were. I guess that is what the hearing later is about. The article did say it wasn't going to be on aircraft parts. and some other stuff.
Just not, as far as I could discern, what was going to be tariffed.
We also have a trade surplus with Brazil.

USA gets 80 percent of its unroasted coffee from Latin America, with Brazil being the largest supplier, accounting for 35 percent of those imports. And ...... although born in Portugal, Carmen Miranda grew up in Brazil, hence "The Bombshell From Brazil" poor lady rolling in her grave to see what has become of her beloved ties to USA. Invited to sing for FDR, and In 1941, she was the first Latin American star to be invited to leave her handprints and footprints in the courtyard of Grauman's Chinese Theatre and was the first South American honored with a star on the Hollywood Walk of Fame. We hang our heads in shame at what the vile felon, grifting, tax-evading, fraud man-baby continues to destroy, over and over ....... and over

Brazilian coffee going up?

The bad news - Trumpmanistan inhabitants pay more.

The good news - other countries will get it cheaper as Brazil seeks out other markets.
