A federal judge has denied a motion to temporarily block a Tennessee law making it illegal to “harbor” undocumented immigrants.

The petition for a preliminary injunction to block the law is a part of a lawsuit filed last year. The suit argues that Senate Bill 392 is unconstitutional and that its broad language could criminalize landlords, churches and nonprofits that house undocumented immigrants. It also contends that enforcement of immigration law should be left up to the federal government rather than the states.
