On Monday, Gov Scott Walker (R) WI, announced he is running for President of the United States. He made the announcement via social media earlier in the day, and later did it in person before a cheering crowd of his supporters.
The raids, according to the article, were called for by a partisan political opponent of Governor Walker's, District Attorney John Chisholm, a Democrat. Staring as an embezzlement investigation, Chisholm expanded his investigation to include many of Walker's allies. This expansion coincided, with the protests and eventual passage of Wisconsin's Act 10.
