Sioux Falls, SD, October 19, 2026 —
A law enforcement operation at a horse racing festival in Wilder, Idaho, resulted in hundreds of detentions and 105 arrests for alleged immigration violations, according to the available account. The American Civil Liberties Union is now challenging the operation in a lawsuit, arguing that it violated constitutional rights and could affect how U.S. Immigration and Customs Enforcement operates nationwide.
The operation was initiated under a warrant for gambling offenses. The summary does not provide details about the warrant, the specific conduct it covered or how authorities connected it to the immigration arrests. It also does not identify the festival, give the date of the operation or state the exact number of people detained.
The arrests are described as being for alleged immigration violations; no further information is provided about the allegations or the status of those arrested. The available account does not specify which constitutional rights the ACLU says were violated, what remedies the lawsuit seeks or where and when it was filed.
The ACLU’s claim that the case could change ICE practices nationwide is an argument made in connection with the lawsuit, not a reported outcome. The summary does not indicate whether a court has ruled on the claims, whether the agency has responded or whether any operational changes have occurred.
Further details about the legal challenge and the operation are not available in the provided information. The lawsuit’s allegations remain claims, and the information supplied does not establish a court finding that the operation violated the Constitution.
