The Obama administration on Tuesday filed suit against Utah, now the fourth State to have an immigration law challenged in federal court.  The suit argues that State efforts to enforce immigration are preempted by federal authority, that the law will disrupt the enforcement of federal immigration law, and that State immigration enforcement efforts must be made in concert with the Department of Homeland Security.  Utah's immigration law is known as H.B. 497, which in part requires the verification of immigration status of individuals arrested for certain crimes. 

Attorney General Eric Holder issued the following comment:

"A patchwork of immigration laws is not the answer and will only create further problems in our immigration system," "The federal government is the chief enforcer of immigration laws and while we appreciate cooperation from states, which remains important, it is clearly unconstitutional for a state to set its own immigration policy."
