In 2006, Pennsylvania passed the Illegal Immigration Relief Act, which fined landlords who rented housing to undocumented immigrants and also fined business owners who hired them. The State of Arizona passed S.B. 1070, which led to racial profiling and required police officers to request legal documentation from anyone they suspected was undocumented. Both laws, along with similar others, were deemed unconstitutional in part because the U.S. Constitution assigns control over immigration to the federal government, not individual states.[29]
