Before becoming a U.S. senator, Tom Cotton served his country in Iraq and Afghanistan. He earned a Bronze Star and was elected to Congress from Arkansas in 2012. Two years later, he defeated a two-term Democrat incumbent to become a 37-year-old senator. And now, in a new book called “Sacred Duty: A Soldier’s Tour at Arlington National Cemetery,” Cotton tells the remarkable story of The Old Guard and its important role as the Army’s oldest active-duty infantry unit. After returning from his Iraq deployment, Cotton served at Arlington with the Army’s official ceremonial unit. The experience led him to research The Old Guard’s rich history and write “Sacred Duty.” He spoke to The Daily Signal about the book.
