On the same day California gave some undocumented immigrants the right to get drivers licenses, Gov. Jerry Brown vetoed legislation that would have provided overtime pay, meal breaks and other labor protections to an estimated 200,000 caregivers, nannies and house cleaners.

Brown called their work a "noble endeavor" and said they deserve fair pay and safe working conditions.

But the Democratic governor said the bill "raises a number of unanswered questions," prompting him to reject the measure. It was among dozens of bills sent to him by the Legislature that he acted on in the final hours before his midnight deadline.
