MADISON, Wis. (AP) -- The Wisconsin Democratic Party has filed an ethics complaint against Republican Gov. Scott Walker over statements he made during a recorded prank call.

In their complaint filed Monday with the Government Accountability Board, the Democrats claim Walker violated campaign finance laws by apparently asking for support for politically vulnerable Wisconsin Republican lawmakers from a caller who he thought was a wealthy campaign donor.

Walker's spokesman, Cullen Werwie, calls the allegations baseless.

The call to Walker was made by a left-leaning website. The caller claimed to be David Koch, one of two billionaire brothers who donate heavily to conservative causes.

Dane County District Attorney Ismael Ozanne said last week that he found nothing about Walker's statements to merit a criminal investigation. He says he hasn't examined allegations of campaign finance violations.

MADISON, Wis. (AP) -- Dane County District Attorney Ismael Ozanne says he won't launch a criminal investigation into either Wisconsin Gov. Scott Walker or the 14 Democrats who fled the state.

Ozanne says there's no evidence that Walker broke the law when he said "we considered" planting agitators in the crowd of protesters. Walker made the statement during a recorded phone call with a blogger who posed as campaign contributor David Koch.

The prosecutor says there's also no evidence the 14 Democratic state senators who fled Wisconsin committed a crime.

Ozanne is now urging state officials to comply with a Dane County judge's order to open the doors of the Capitol to the general public. Department of Administration officials say they're in compliance with the order but have continued to limit access.

The Dane County DA will not launch a formal criminal probe of a phone call between Gov. Scott Walker and the man who posed as David Koch.

Ismael Ozanne, DA, said in a mid-day press conference: "At this time I do not find any criminal liability."

For 10 days now crowds have gathered in and outside of the Capitol cheering, chanting and, for the most part, remaining peaceful.

"I think so far that has happened. "

Now, Madison Police Chief Noble Wray is worried that streak may be in jeopardy.

Wednesday we learned about the prank call involving Governor Scott Walker. A man pretending to be billionaire David Koch called and suggested to Gov. Walker during a 20 minute conversation that he insert trouble makers into the crowd. Gov. Walker said that was considered, but ultimately shot down. And that is why Police Chief Wray is upset.

" You should never even consider...you should be advocating those conditions that put everyone in the best position to be safe."

Wray says he wants to give Gov. Walker the chance to clarify his statements. He adds that he's not doing this to further his own political agenda.

" I did not enter into the political realm. He entered into the public safety realm. When he entered into the public safety realm I feel compelled that I need to say something."

Chief Wray says so far he hasn't any contact with Gov. Walker or Gov. Walker's office. He says if he doesn't get a response he won't be upset, he'll be a professional.

Chief Wray says, " I'm a 27 year professional and I will work with anyone. "

NBC15 News did contact Gov. Walker's office for a comment. We were referred to his press conference yesterday where Gov. Walker defended the statements made in that prank phone call.

" The thing's I've said are things I've said publicly all along. The fact of the matter is people have brought up all sorts of different options and as you saw if you listened to the tape we put that down. "

Chief Wray says he has not personally reached out to Gov. Walker or his office. So far the two sides have not met.

As we reported Wednesday, Governor Scott Walker took a prank phone call earlier this week. He thought he was speaking with David Koch when in reality he was being recorded by the editor of the news website "Buffalo Beast." In that phone call, Walker revealed his supporters considered bringing in outside agitators to stir up trouble with protesters, but he dismissed that idea.

In response to this development, Madison Police Chief Noble Wray issued this statement:

“I spent a good deal of time overnight thinking about Governor Walker’s response, during his news conference yesterday, to the suggestion that his administration ‘thought about’ planting troublemakers among those who are peacefully protesting his bill. I would like to hear more of an explanation from Governor Walker as to what exactly was being considered, and to what degree it was discussed by his cabinet members. I find it very unsettling and troubling that anyone would consider creating safety risks for our citizens and law enforcement officers. Our department works hard dialoging with those who are exercising their First Amendment right, those from both sides of the issue, to make sure we are doing everything we can to ensure they can demonstrate safely. I am concerned that anyone would try to undermine these relationships. I have a responsibility to the community, and to the men and women of this department - who are working long hours protecting and serving this community – to find out more about what was being considered by state leaders.”

The Madison Police Department also released the following statement:

“The men and the women of the Madison Police Department train for crowd situations where an agitator or provocateur may try to create safety risks for citizens and officers. During the demonstration around the Capitol Square no such situation has arisen. Crowd behavior has been exemplary, and thousands of Wisconsin citizens are to be commended for the peaceful ways in which they have expressed First Amendment rights.”

Wis. governor: Prank call won't be a distraction

MADISON, Wis. (AP) -- Gov. Scott Walker says he won't be distracted by a prank phone call made by a blogger posing as one of his campaign donors, and he'll push forward with a bill to limit the power of public employee unions.

Walker stood by his comments on the call, saying they were no different than what he has said publicly.

A website called the Buffalo Beast posted audio of Tuesday's call in which its editor pretended to be conservative billionaire David Koch, who had supported Walker's campaign. On the call, Walker talked about his strategy to pressure Senate Democrats who fled to Illinois to return to Wisconsin to vote on the bill.

Walker revealed his supporters considered bringing in outside agitators to stir up trouble with protesters, but he dismissed that idea.

On the call, Walker talks about his strategy in the state's ongoing battle over union rights and revealed plans to pressure Senate Democrats to come back to Wisconsin.
