President Trump has brought the United States one step closer to a devastating trade war with Mexico, saying talks with Mexican officials at the White House Wednesday ended without a deal. Trump has threatened to impose 5% tariffs on all imports from Mexico beginning Monday unless it agrees to crack down further on Central American migrants bound for the U.S. Trump’s plans have drawn resistance even within his own party—with Republican leaders including Mitch McConnell threatening a congressional revolt. Democratic House Speaker Nancy Pelosi, fresh off a meeting with Mexico’s foreign minister,denounced Trump’s tariff plans.

Speaker Nancy Pelosi: “I think that this is dangerous territory. This is not a way to treat a friend. It’s not a way to deal with immigration. It’s not a way to deal—meet the humanitarian needs at the border.”
