A branch of the U.S. Immigration and Customs Enforcement (ICE) will help with security for the Winter Olympics in Italy, it confirmed Tuesday, sparking anger and warnings they were not welcome.

Reports had been circulating for days that the agency embroiled in an often brutal immigration crackdown in the United States could be involved in U.S. security measures for the Feb. 6 to 22 Games in northern Italy.

“At the Olympics, ICE’s Homeland Security Investigations (HSI) is supporting the U.S. Department of State’s Diplomatic Security Service and host nation to vet and mitigate risks from transnational criminal organizations,” ICE said in a statement.
