A Hill article by Ryan Mancini reports that President Trump reacted to reports of more than 1,000 migrants heading toward the U.S. from Mexico, tying the caravan to Republicans' 2026 midterm losses and warning on Truth Social that tariffs on Mexico would be "IMMEDIATELY DOUBLED" if it is not stopped. Reuters reports around 1,500 people left Tapachula on 10 November, and the article notes Trump replaced chief of staff Susie Wiles with immigration hard-liner Stephen Miller after saying his deportation crackdown may have been "too tough" in the midterms.
