PIERRE, S.D. (AP) — A House panel has voted down a bill aimed at requiring ballot measure campaigns to disclose their donors while supporters gather signatures to qualify for the ballot.

The House State Affairs Committee voted Wednesday to reject the measure.

Democratic Sen. Reynold Nesiba, the sponsor, argued it would close a "loophole" in South Dakota campaign finance reporting.

It would have required initiative campaigns to submit new finance reports by July 1 in odd-numbered years when supporters collect names needed to send initiatives to the voters.

Current state rules don't require the campaigns to disclose their donors until long after they've submitted their signatures to the state to qualify for the ballot.

House Speaker Mark Mickelson, who pushed to shelve the bill, says he supports the objective but didn't think the measure would work as intended.
