U.S. Lawmakers Seek Answers on Canadian Man’s DNA Obtained by Border Officers

Recent events have sparked significant concern among U.S. lawmakers regarding the treatment of a Canadian citizen at the U.S. border. Kevin Larson, a 68-year-old retired health physicist, was held for three hours at the Blue Water Bridge on October 18, 2025, and was reportedly coerced into providing a DNA sample.
Incident Summary
Larson attempted to enter the U.S. to attend the “No Kings” rally in Port Huron, Michigan. He aimed to show solidarity and express his concerns about the current U.S. administration’s stance towards Canada. Despite his intentions and clean record, Larson was denied entry.
Lawmakers Demand Answers
U.S. Rep. Debbie Dingell, alongside Rep. Jamie Raskin, has expressed outrage over the incident. They sent a letter to the Department of Homeland Security, the Department of State, and the Department of Justice, seeking clarifications on the legality of the DNA collection process.
Details of the Encounter
- Larson was selected for secondary inspection upon arrival.
- Border officers conducted extensive questioning and searched his possessions.
- He was required to sign a form denying support to foreign terrorist organizations.
Coercion for DNA Sample
In a surprising turn, customs officers informed Larson that he must provide a DNA sample or face legal charges. Despite his protest that this was a violation of privacy, Larson eventually complied due to concerns about potential repercussions.
Concerns Over Border Policies
The U.S. Customs and Border Protection (CBP) has established a directive regarding DNA collection from individuals arrested on federal charges. However, this is not typically applicable to lawful entrants. Larson, holding a valid Canadian passport, contests the rationale given for his denial.
Request for Transparency
Dingell and Raskin are seeking answers on several key points:
- The legal justification for collecting DNA samples.
- Records of similar incidents involving other individuals.
- The storage methods and process for removing DNA samples from databases.
Response from Authorities
The lawmakers emphasize the need for clarity, as they have yet to receive a response to their inquiries. Larson’s experience raises broader concerns about U.S.-Canada relations, especially under the current administration.
Future of U.S.-Canada Relations
Despite his recent experience, Larson remains hopeful about the future of relations between Canada and the United States. He views the two countries as longstanding allies and expresses a desire to see improved interactions.
As Larson recounts this troubling experience, he emphasizes how critical it is for both nations to recognize their shared history and connection. Until conditions change, he and his wife have decided to pause their visits to the U.S. for the time being, choosing instead to host their family in Canada.
