Former Arizona U.S. Sen. Jon Kyl to replace John McCain

PHOENIX (AP) - Prolonging the uncertainty over who will fill the late John McCain's U.S. Senate seat, the governor of Arizona on Tuesday announced the appointment of former Sen. Jon Kyl but said he has only committed to serve until the end of the year. Kyl, a Republican who retired from the Senate in 2012 to spend more time with his family, is currently shepherding Trump's nomination of Brett Kavanaugh to the U.S. Supreme Court. Kyl's appointment will make it possible for him to vote for the nomination.
