During consideration of the bill to extend unemployment benefits (H.R. 4213), Sen. Jim DeMint (S.C.) offered a measure to recommit the bill to the Judiciary Committee with instructions to include language that no funds in any provision of law may be used to participate in a lawsuit against Arizona's immigration law. The Obama administration opposes the Arizona law (S.B. 1070) despite the fact that it does not actually create new powers of government but instead makes illegal under state law the illegal immigration that is already illegal under federal law.
Arizona (like any other state) has the right to stem the tide of illegal immigration into the state.
