I commend President Obama for his leadership in immigration. The Justice Department has filed a lawsuit challenging the constitutionality of Arizona's anti-immigrant law, SB1070. The President is demonstrating his commitment to comprehensive immigration reform, one of our top priorities. His challenge of SB1070 is preventing a patchwork of immigration-related state laws that could lead to rampant racial profiling throughout our country, but that does little to fix our broken immigration system.
