The fatal shooting of a 37-year-old Minnesota mother by a U.S. immigration agent has rattled Minneapolis and much of the country, raising fears it could become another flashpoint in an already polarized United States.

State and federal officials offered starkly different accounts of the shooting, in which an unidentified officer killed U.S. citizen Renee Nicole ​Good in her car Wednesday, while immigration officers were carrying out ‍what federal officials have called the "largest DHS operation ever" by the Department of Homeland Security.

With 2,000 federal officers deployed across the Twin Cities of Minneapolis and Saint Paul, thousands of people gathered in Minneapolis to protest the shooting, while demonstrations were called in New York, Chicago, Seattle, Phoenix, Orlando, ‌and Columbus, Ohio.

The Minnesota operation, which includes U.S. Immigration and Customs Enforcement officers, is part of Republican President Donald Trump's ‍nationwide crackdown on migrants and a politically charged investigation into fraud allegations against some Minnesota nonprofit groups in the Somali community.

At least 56 people have pleaded guilty since federal prosecutors under the previous Democratic administration of Joe Biden, started investigating childcare and other social service programs in the Somali community.
