The bill hasn’t yet been scheduled for another vote.
The bill would require political parties to provide the candidate’s birth certificate.
If these requirements aren’t followed, the candidate’s name won’t appear on the ballot.

Hawaii officials have repeatedly confirmed Obama’s citizenship, and his Hawaiian birth certificates have been made public.
