In May 2011, Senate President Russell Pearce explained why he thinks the hardships Arizona faces from illegal immigration should allow the state to start enforcing SB 1070, the state's immigration law approved in 2010, but placed on hold by a federal judge. On Monday, the U.S. Supreme Court ruled Arizona can require police to check the immigration status of those they stop, one of the more controversial provisions of SB 1070.
