President Donald Trump’s administration has instructed U.S. prosecutors to criminally investigate state and local officials who obstruct federal immigration enforcement efforts.

According to a memo obtained by Reuters, the directive aims to target officials accused of implementing sanctuary policies or otherwise resisting federal immigration laws. This move is part of the administration’s broader crackdown on illegal immigration and efforts to enforce stricter compliance at state and local levels.

Critics argue that the policy could deepen tensions between federal and local governments, while supporters view it as a necessary step to uphold the rule of law. The Justice Department has not yet commented publicly on the memo.
