Republican governor candidate Al Olszewski, a state senator from Kalispell, has picked a fellow state senator as his running mate.
State Sen. Kenneth Bogner, of Miles City, will be the lieutenant governor candidate.
Bogner was a combat engineer in the U.S. Marine Corps and has a master's degree in public policy. He has also worked as a staffer in the state Senate and as a field representative for U.S. Sen. Steve Daines.
In a press release, Bogner said it was a "great honor" to run with Olszewski.
"I respect Al's service to our country and state. I look forward to helping him pass meaningful reforms to state government, writing a sustainable budget, building up our rural and natural resources communities, standing up for the sanctity of human life and our constitutional rights," Bogner said in a statement.
Campaign finance reports for the third quarter of the year are due Saturday.
In reports filed over the summer, Gianforte in one month out-raised both Fox and Olszewski over the quarter. Gianforte brought in, not including a $50,000 loan he gave his campaign, nearly $340,000. Fox raised about $225,500. Olszewski captured about $32,500 and loaned himself $100,000.
