Travelers headed north into Bend were treated to a mischievous political spectacle Tuesday night, in the form of a flashing road sign bearing an anti-Hillary Clinton message.

"PREPARE TO SLOW," flashed on the variable message sign, followed by, "HILLARY FOR PRISON."

The political message, presumably the work of a vandal, was on display on U.S. 97 less than five miles south of the High Desert Museum. Retired Woodburn police Sgt. John Mikkola shot the video just north of milepost 150 and provided it to The Oregonian/OregonLive.

The sentiment rails against Clinton, the Democratic presidential nominee, and is notably promoted in button form in the "Trump Make America Great Again Committee" online store.

Peter Murphy, an Oregon Department of Transportation spokesman in Bend, said a contractor owns the flashing sign.

The contractor, he said, was aware of the political message early Wednesday morning and corrected the problem.

The sign, Murphy said, is now locked up.
