John Morton, the Department of Homeland Security Assistant Secretary who heads ICE, visited Chicago yesterday and promised to ramp up immigration enforcement. Then, he said this (link):

Echoing comments by President Barack Obama and others in the administration, Morton said that Arizona's new law targeting illegal immigration is not "good government." The law makes it a crime to be in the state illegally and requires police to check suspects for immigration paperwork.

Morton said his agency will not necessarily process illegal immigrants referred to them by Arizona officials. The best way to reduce illegal immigration is through a comprehensive federal approach, not a patchwork of state laws, he said.

"I don't think the Arizona law, or laws like it, are the solution," Morton said.
