An Arizona House committee has approved a bill that would remove authority from the Arizona Citizens Clean Elections Commission to investigate campaign contribution violations.

The Senate-approved bill would allow only the Secretary of State and state Attorney General to investigate and act on violations.

The Arizona House Committee on Judiciary approved the Senate Bill 1344 by Sen. Steve Pierce of Prescott with a 4-2 vote Wednesday.

Supporters say state statute does not grant the commission authority to investigate possible campaign contribution violations.

The commission said voters granted authority to enforce campaign contribution limits when it approved the Citizens Clean Elections Act in 1998. The act allows candidates to receive full funding for their campaigns if they forgo private donations and receive a certain number of $5 donations.
