Arizona: Joe Lieberman

Barack Obama's pick to head the U.S. Department of Homeland Security promised a Senate panel Thursday to do more to deal with employers who knowingly hire undocumented workers.

But Janet Napolitano told members of the Senate Committee on Homeland Security and Government Affairs that she can't promise them that more companies will be prosecuted. That decision, she said, is made by the Department of Justice.

During the hearing of more than two hours, Napolitano said she supports the goal of a federal law which requires states to come up with more secure driver licenses. She even signed an agreement as governor with the agency she hopes to head to have Arizona produce those licenses.

U.S. Sen. Jon Kyl (R-Phoenix) and U.S. Rep. John Shadegg (R-Phoenix) told PolitickerAZ.com Saturday they recognize that Republicans are likely facing a serious deficit in the number of seats they will hold in the 111th Congress, but said the GOP can still have a major hand to play in the agendas of the House and Senate.
