A former Democratic legislator has filed to run against Gov. Steve Bullock in the June 7 primary.

Bill McChesney, a former Miles City representative, filed his paperwork with the Secretary of State's office late Friday. The candidate filing deadline is Monday.

The former legislator from Miles City may be challenging Bullock, but he's a supporter, too.

Records show McChesney has already donated $50 toward the governor's re-election campaign, as well as $150 to Bullock in 2012. McChesney did not immediately return a call for comment.

McChesney's entry into the race allows Bullock to spend $666,642 in campaign contributions he has in the bank earmarked for the primary.
