Arizona Gov. Jan Brewer speaks to the media after arguments at the U.S. Supreme Court, on April 25, 2012 in Washington, DC. Brewer strongly supported SB 1070, parts of which were struck down by the Court today.

The Supreme Court ruling on Arizona's anti-illegal immigration law upheld one provision of SB 1070, but struck down three others. Strong opponents of illegal immigrations championed Arizona's law, and those that followed in Alabama and Georgia.

Reaction from anti-immigration activists today emphasize the positive, that the "check-your-papers" provision stands.

We haven't come to a national consensus on immigration, says Steven Camarota of the Center for Immigration Studies. Once Americans have finished answering the big questions, federal policy will follow.
