Amazon continues to deflect questions regarding a possible relationship with U.S. Immigration and Customs Enforcement (ICE) amid concerns over the company’s facial recognition technology and its use by the government.

The issue again came to the forefront Wednesday when representatives for Amazon appeared before the New York City Council.

According to BuzzFeed News, Brian Huseman, Amazon’s vice president for public policy, declined to disclose whether ICE was a client but made specific mention of the company’s “Rekognition” technology when questioned by Council Speaker Corey Johnson.
