ProPublica's investigation found that immigration agents detained more than 170 U.S. citizens against their will during the first nine months of President Donald Trump's second administration, including nearly 20 children, some as young as those with cancer diagnoses. Citizens reported being held for over a day without access to lawyers or family members, and some experienced physical mistreatment including being dragged, tackled, beaten, tasered, and shot by agents. The government does not officially track how often immigration agents detain American citizens, prompting the news organization to compile its own count from available cases.
