JUNEAU, Alaska — In his third attempt at filling an open Alaska Senate seat, Gov. Bill Walker has appointed Mike Shower of Wasilla.

Shower was among the names advanced by Republicans following a messy process in which Senate Republicans rejected Walker’s first pick and his second pick withdrew amid a firestorm over controversial social media posts.

Walker’s office said Tuesday that Walker was not aware of Thomas Braund’s controversial posts, which his office said would have disqualified Braund from consideration. Walker’s office asked Republicans for the additional names after Braund withdrew.

Shower is subject to confirmation by Senate Republicans.

His resume states that Shower is retired from the U.S. Air Force and is a pilot with FedEx.

If confirmed, he would replace Wasilla Republican Mike Dunleavy, who resigned to run for governor.
