As the 118th United States Congress convenes for the first time on Tuesday, its upper chamber is marking a record broken by Senator Mitch McConnell, who has become the longest-serving Senate leader in history.
McConnell, an 80-year-old Republican from Kentucky, has surpassed the late Democratic Senator Mike Mansfield’s record of 16 years. McConnell has served as Republican party leader in the Senate since 2007.
