McCain: I'm not sure if Arizona's immigration law is legal

Although McCain had sounded a note of support for the bill, calling it a “good tool” for law enforcement, he stopped short of fully endorsing the measure. “I haven’t had a chance to look at all the aspects, but I do understand why the Legislature would act,” he said. Even though it wasn’t clear to him “whether all of it is legal or not,” he said state lawmakers “acted out of frustration because the federal government didn’t do its job.”
