Walker’s chief of staff resigns

MADISON, Wis. (AP) — Gov. Scott Walker’s chief of staff who helped guide the administration during the tumult over public-employee unions and passage of his first state budget is stepping down.

Keith Gilkes says he’s resigning as of Oct. 8 to return to his business as a political consultant. He says he may get involved if Democrats try to recall Walker.

Gilkes says his resignation is unrelated to an ongoing secret investigation that stemmed from questions of whether current and former Walker aides took part in political activity on taxpayer time. He says he just felt the time was right to return to the private sector.

Cullen Werwie, one of Walker’s spokesmen, has been granted immunity in the probe. FBI agents earlier this month raided the home of Walker aide Cynthia Archer.
