Your countries are being ruined."The president said the U.N. is "funding an assault on Western countries and their borders.""The U.N. is supporting people that are illegally coming into the United States, and we have to get them out," Trump said. "The U.N. also provided food, shelter, transportation and debit cards to illegal aliens."The UN is supposed to stop invasions not create them and not finance them."TRUMP'S FINAL CABINET PICK, MIKE WALTZ, CONFIRMED BY SENATE IN NARROW VOTETrump said illegal immigrants are also "pouring into Europe.""It is not sustainable and, because they choose to be politically correct, they are doing absolutely nothing about it," Trump said. "Your countries are going to hell. In America, weve taken bold action to swiftly shut down uncontrolled migration."Once we started detaining and deporting everyone who crossed the border and removing illegal aliens from the United States, they simply stop coming. They're not coming anymore," Trump said, while thanking El Salvador for "receiving and jailing criminals" who entered the United States.This is a developing story. Check back soon for updates.
