On today's episode of Politics Nation, Reverend Al Sharpton discusses the breaking news: President Trump announced a deal after EU talks, amid his trip to Scotland for golf. The big question is how this impacts U.S. states and cities, which are facing economic uncertainty and social upheaval due to shifting trade policies and deportations. I'll ask Colorado Governor Jared Polis soon. Later, we explore challenges for America's mayors with the Mayor's Association President and a promising candidate for Minneapolis' next mayor. I'll also critique Trump's new executive order on homelessness, which I believe will worsen the problem.
