Several sources report Arizona's Republican governor will announce the appointment of former Sen. John Kyl to replace the late Sen. McCain. Before retiring, Republican Kyl won three Senate terms in AZ and is popular there.
Given his age and prior retirement, Kyl is unlikely to run for a full term in 2020. He is an uncontroversial choice and already has the endorsement of Sen. McCain's widow.
In retirement, Kyl has handled various ad hoc jobs for the Trump White House and is on relatively good terms with the President. He will be sworn in soon, in time to vote for the Kavanaugh nomination.
