Brazilian President Luiz Inacio Lula da Silva is coming out fighting against President Trump's extraordinary threat of 50% tariffs. Trump's tariffs are mostly slapped on nations that have a trade surplus with America. But Brazil has a trade deficit. So why?

The current Brazilian president joins the show from Brasilia for an exclusive interview, and says it's unacceptable for the USA, or any foreign government, to interfere in their internal affairs and their judicial process, and the best way to discuss any trade issues is around the negotiating table.   Also on today's show: Ami Ayalon, former director, Shin Bet; author Lizzie Wade ("Apocalypse")    Learn more about your ad choices.
