What legal options does the federal government have when dealing with jurisdictions that obstruct federal immigration enforcement?

According to constitutional law expert Jonathan Turley, the federal government has legitimate grounds to withhold grants from jurisdictions that actively undermine federal enforcement efforts. He argues there is no legal obligation for the federal government to fund jurisdictions that obstruct federal immigration law. Turley emphasizes that this approach requires litigation on multiple fronts to be effective. The legal strategy involves both pursuing charges against officials who obstruct federal law and leveraging federal funding as a compliance mechanism. This dual approach addresses the ongoing constitutional tension between state and federal authority in immigration enforcement matters.
