A U.S. citizen who voted for Donald Trump was detained by armed immigration agents during a stop in Virginia in March. A toddler, his mother, and his grandmother, all U.S. citizens from Puerto Rico, were detained while speaking Spanish while shopping in Milwaukee. U.S. citizen members of the Navajo Nation were stopped and questioned in Arizona and New Mexico.
These are just some of the immigration-related incidents that have raised alarm among members of Congress and prompted them to reach out to the Trump administration for more information.
