HELENA - A tip from a motorist led authorities last week to arrest former Montana Secretary of State Brad Johnson for drunken driving, Broadwater County Attorney John Flynn said Thursday.
Flynn said another motorist called to report Johnson, who is a Republican candidate for the Public Service Commission, which regulates utilities and phone companies.
"It was someone on the road," he said.
Johnson was cited for drunken driving and failure to drive in his own lane on May 20. A breath test administered shortly after his arrest showed his blood-alcohol content at 0.24 - or three times the legal limit for driving.
Johnson has said he is not guilty of drunken driving. He has not yet made an initial court appearance.
Johnson was arrested around 10 p.m. a few miles from his East Helena home after driving home from Bozeman, where he said he'd a few drinks and had been dancing.
He served as secretary of state from 2005 through 2008, when he lost his re-election bid to Democrat Linda McCulloch.
He is now running in a contested Republican primary in PSC District 5 against Helena lawyer Bill Gallagher. The winner will run against incumbent Democratic Commissioner Ken Toole.
