MADISON, WI (WTAQ) - Governor Scott Walker’s legal defense fund only has about $5,000 left.

And there’s talk that he might be shutting it down, as a John Doe investigation into his former Milwaukee County aides appears to be grinding to a halt.

According to new campaign records, the Republican Walker put $40,000 of campaign donations into his defense fund late last year, which made the total around $200,000.

Nicole Tieman of the Walker campaign tells the Journal Sentinel that the latest transfer pays for work that was done to cooperate with authorities over the last year.

Most of the $200,000 was given to Milwaukee defense attorney Michael Steinle and Chicago lawyer John Gallo, who represented Walker in the investigation that resulted in six criminal convictions.

Three former aides in Walker’s former Milwaukee County executive office were convicted, along with another Walker appointee, a campaign donor, and a domestic partner of a former aide.

Most were either convicted of embezzling money from a veterans’ program, or illegally doing campaign work on taxpayers’ time.
