In Arizona, a bill (SB1265) is pending that would deny bail to "illegal immigrants" who have been charged with certain felonies. It awaits a final vote in the Arizona House. This bill is based on Proposition 100, which was passed by voters in 2006 (with 78% of the vote) and which amended the Arizona Constitution. See also this Arizona Daily Star story.

UPDATE: The Arizona House has passed SB1265 by 34-22. The bill now goes to the state Senate. See also this story.
