Washington D.C. website Politico has dropped another surprise in the Republican primary for an Oregon U.S. Senate seat.

The site released a 2013 police report detailing the disintegration of a relationship between candidate Monica Wehby and her biggest financial backer, timber baron Andrew Miller.

The Portland Police report shows Miller accused Wehby—then his girlfriend—of "stalking" and "harassing" him, and talked about filing a restraining order.

"He told me that he wanted to initiate a police report because WEHBY has been 'harassing' his employees and 'stalking' him," says the report by Portland Police officer Brent M. Taylor. "He told me that he intended to get a stalking order tomorrow against WEHBY.

"I asked MILLER what WEHBY had done specifically to make him desire to get a stalking order," the report continues. "He told me that WEHBY has showed up at his home uninvited about 5 times within the last 10 days."

While the police report is embarrassing for Wehby, it may help vindicate her from a federal election complaint filed by the Democratic Party of Oregon earlier this month. The complaint charged Webhy's campaign of illegally coordinating with Miller, citing their romantic involvement.

This report seems to show they broke up in April 2013—well before she began campaigning.

Wehby, a pediatric neurosurgeon, is the frontrunner in the GOP race for U.S. Senate—polls show her leading Rep. Jason Conger (R-Bend). The winner of the GOP primary is likely to face U.S. Sen. Jeff Merkley (D-Ore.) in the fall.

Miller owns Stimson Lumber in Washington County, and is one of Oregon's biggest Republican political donors. WW profiled his efforts to overthrow state politics two years ago—a revolt that succeeded in Clackamas County.

Both Wehby and Miller told Politico the report was insignificant.

“The first time I ever learned of this report was this evening and there really isn’t much to it of consequence,” Wehby said in her statement. “A year ago I went through the process of concluding a relationship. That relationship ended amicably, and while I’m not pleased that it has been deemed newsworthy, I guess that is the cost of challenging the political status quo.”In an interview, Miller said he now regrets calling the police on Wehby. The couple had dated for about two years, but broke up in 2013. Miller, who is divorced with four children, said they remain friendly.“There was a week there or so when we were breaking up that people can be emotional. And me included,” Miller said. “If I think back to that period of time, I regret saying those things in that light.”
