After ProPublica Investigation, House Democrats Demand Answers on U.S. Citizens Detained by Immigration Agents

According to ProPublica's recent investigation, House Democrats are demanding answers from the Trump administration regarding the detention of hundreds of U.S. citizens by immigration agents. In an October letter to Department of Homeland Security Secretary Markwayne Mullin, 40 legislators from California and other states requested the administration provide the number of citizens detained by immigration agents and details on how the government verifies citizenship and legal status during immigration operations.

Experts have stated that the cases highlight the federal agents' overreach of constitutional rights for citizens.

ProPublica found more than 500 Americans detained by immigration agents, though the actual number is likely an underestimate since the government does not transparently track such cases. The investigation uncovered cases where over 100 Americans were questioned about their citizenship, 63 detained while recording, 36 held for at least a day without access to a lawyer or family, and roughly a dozen citizens deported, mostly children.

DHS has consistently maintained that it is not arresting U.S. citizens and has defended its immigration operations as "highly targeted."

House Democrats have been pressuring the second Trump administration for more details on this issue since early 2025. Last year, congressional Democrats launched a broad investigation into immigration agents' detention of U.S. citizens following ProPublica's reporting that revealed over 170 citizens had been detained by immigration agents.

Recently, Rep. Teresa Leger Fernández, a New Mexico Democrat, introduced the Justice for Citizens Wrongfully Detained by ICE Act, a bill aimed at making it easier for citizens to sue immigration agents for wrongful arrests.
