MILWAUKEE (AP) -- A 12th witness has been granted immunity in a secret Milwaukee County investigation that has already led to criminal charges against five people close to Gov. Scott Walker.
Online court records say David Halbrooks was granted immunity Wednesday. Halbrooks declined comment when reached by The Associated Press.
The website of Milwaukee law firm Maistelman & Associates Inc. lists Halbrooks as an "of counsel." The term generally refers to an outside lawyer who provides specific legal expertise to a law firm.
The secret investigation involves allegations that some people close to Walker campaigned on county time and others embezzled money from a veterans program. The governor has not been charged with wrongdoing and says he's cooperating with the investigation.
Other witnesses who have been granted immunity include Walker spokesman Cullen Werwie.
