Back in the United States, Vice President Mike Pence administered the oath of office Wednesday to former U.S. Senator Jon Kyl, who fills the Senate seat left vacant after the death of Arizona’s John McCain last month. Kyl is a Republican who represented Arizona in the Senate for 18 years. After retiring from Congress in 2013, Kyl joined the prominent law firm Covington & Burling, where he worked as a lobbyist on behalf of clients from Wall Street, Big Pharma and the weapons industry. Kyl also worked to advance Judge Brett Kavanaugh’s Supreme Court nomination through the Senate. Kyl has said he will serve as Arizona’s junior senator until a special election in 2020.
