MILWAUKEE (AP) – A former appointee of Gov. Scott Walker convicted of embezzling money from a veterans’ group has been sentenced to two years in prison.    A jury found Kevin Kavanaugh guilty of theft in October after prosecutors said he stole more than $51,000 intended to help veterans and their families.  The 62-year-old Kavanaugh apologized in Milwaukee County Circuit Court Friday, but Judge Michael Guolee called the apology “worthless.” Kavanaugh will also serve two years of supervision after his prison sentence and must pay more than $51,000 in restitution.  As Milwaukee County executive, Walker appointed Kavanaugh to head the county Veterans Service Commission. Prosecutors say Kavanaugh skimmed money from phony withdrawals from a veterans-service organization.   Kavanaugh is the fifth Walker aide or associate to be convicted as part of a secret probe, and a sixth is awaiting trial.
