The White House posted a short video on its official account on X that borrows imagery from the children’s series “Teletubbies” and delivers a stern warning to people living in the United States without legal status. A Spanish-language description of the clip quotes the narrator saying, “Voy a decir que si estás en el…,” before the sentence is cut off, leaving the threat implicit. The post quickly drew criticism from social-media users who called the tone both mocking and menacing. Separately, President Donald Trump is scheduled to deliver remarks from the Oval Office at 1 p.m. Eastern time on Thursday, according to multiple announcements issued late Wednesday. The White House has not disclosed the subject of the address, but the speech comes amid heightened attention to the administration’s messaging on immigration.
