HELENA, Mont. -

Montana Lt. Gov. John Walsh says he will travel to Washington, D.C., on Monday and will be sworn in the as the state's new Senator on Tuesday.
    
After his appointment today by Gov. Steve Bullock, Walsh said he would not be "sucked in" to the political culture of Washington.
    
The 53-year-old Walsh already was a candidate to replace Baucus in this year's elections, and his interim appointment may boost the Democrat in a potential general-election campaign against Republican U.S. Rep Steve Daines.
    
Walsh spent 33 years in the Montana National Guard, rising to adjutant general in 2008. In 2012, the Democrat resigned from that post to run on the bottom half of the Bullock ticket.
    
Montana Republican Party Chairman Will Deschamps called the Walsh appointment a "back-room deal" that put politics ahead of what is right for the state.
