One of the largest financial backers of Ballot Measure 1 has been fined nearly $340,000 for late campaign spending reports.

Alaskans for Open Government spent thousands of dollars on Clean Team Alaska and its support for the initiative that would prohibit the use of public funds to lobby or campaign.

Ballot Measure 1 would also prohibit holders of government contracts and family members from making political contributions.

Ken Jacobus of Alaskans for Open Government told KTUU-TV in Anchorage the fine by the Alaska Public Offices Commission resulted from a series of disagreements over filing requirements.

But Josh Applebee, campaign manager for the Ballot Measure 1 opposition group Stop the Gag Law, told KTUU that a group like Alaskans for Open Government should be the first to disclose all income and spending.
