The Department of Justice sent a letter to Clark County Friday asking for proof of compliance with immigration enforcement.
The letter, which was sent to eight other jurisdictions, threatens to withhold a federal grant unless government agencies can prove they are not protecting undocumented immigrants.
Clark County currently receives $975,604 from the federal grant in question.
Clark County released a statement in response which reads in part:
"Clark County is in compliance with this code and will respond to the Department of Justice accordingly. Clark County is not a 'sanctuary county,' despite its inclusion on some lists. As a body, it has never expressed support for any movement that promotes the violation of any federal statute or regulation that provides federal agencies authority in the field of immigration law enforcement."
The statement goes on to state that the county is often included on lists of sanctuary cities and counties "based, apparently, on concerns local law enforcement expressed over a particular ICE program that presented constitutional concerns."
The Las Vegas Metropolitan Police Department declined to comment.
