ProPublica's "More Than Numbers," reported by Sarahbeth Maney and Nicole Foy with photos by Maney, identifies more than 500 U.S. citizens detained by immigration agents since Trump returned to office, profiling cases including a 79-year-old car wash owner knocked to the ground, a autistic teenager's sister, and an Iraq veteran held three days without charges. The Department of Homeland Security denies detaining Americans and says citizens are released once identified.
