On August 23, the California Assembly Appropriations Committee passed SB 149.  This is the bill that forces candidates running in a presidential primary to reveal their income tax returns.  The bill had already passed the Senate and had already passed the Assembly Elections Committee, so now it goes to the Assembly floor.  The vote was 10-5.

Although bills to require presidential candidates to reveal their income tax returns had been introduced in several states this year, the California bill seems to be the only such bill that is likely to pass.  It would have no effect on independent presidential candidates.
