BIRMINGHAM, Ala. (AP)  A quarrelsome U.S. Commission on Civil Rights held its first hearing on state laws that target illegal immigration, with Republican backers arguing Friday that the measures are vital to protecting American jobs and fighting crime.

Kansas Secretary of State Kris Kobach, who helped write similar immigration laws in Arizona and Alabama, said unemployment in Alabama has dropped three times faster than the national average since parts of the state’s law took effect last fall — a change he credited at least in part to the act.
