They'll sue Arizona, though.

A Justice Department official confirmed in a news report this week that the agency will not take any action against cities that defy a 14-year-old federal law by offering illegal immigrants sanctuary. The measure (Illegal Immigration Reform and Immigration Responsibility Act of 1996) specifically requires states and municipalities to cooperate with federal authorities when it comes to immigration enforcement.

The suit against Arizona claims that Arizona is violating that same statute by instructing its peace officers to detain illegal aliens for the government.

I'm not too impressed with Eric Holder's legal acumen or plain critical thinking skills.
