HELENA, Mont. (AP) — A bipartisan measure backed by Gov. Steve Bullock to force more disclosure on money in politics has hit a roadblock.

A Republican-controlled House committee tabled Senate Bill 375 on Monday. The full House later rejected an effort to override the decision and bring it to the floor.

Supporters argue it is needed to crack down on so-called dark money political groups.

Opponents argue anonymity is an important part of political speech in the country, and say the measure won't really solve any problems.

A different House committee advanced two GOP-backed ballot initiatives.

One would end same-day voter registration, and another would change elections so that only two candidates face each other in the general election.

Both sides expect the bills would help Republicans in statewide elections.
