— Manchester on protecting the city.
Arthur Manchester was the former Majority Leader of the Continental Congress and the first Vice President of the New United States. Charged with finding the Charleston mole in season 3, he is killed by the mole (later revealed as Lourdes, under alien control). He was Tom Mason's former mentor and history professor before the invasion.
Arthur Manchester was the Chair of the American History Department at Boston College, and one of Tom Mason's professors. At some point he wrote From Darkness, Democracy, a book on the American Revolution.
After the invasion, he helped found the Charleston community and government and was elected Majority Leader. However, his overcautious attitude and his desire to keep Charleston hidden until they could consolidate was seen as reckless by Tom and Daniel Weaver who believed that, with the Skitter Rebellion, they had a real chance to fight back effectively against the Overlords.
Arthur had the whole 2nd Mass arrested when they attempted to meet with the rebels. However, General Bressler, the head of the Charleston military, disbanded the civilian government and arrested Manchester. He was later released and the civilian government restored on the condition that he resign as Majority Leader, an offer with which he complied.
After Tom's election to the presidency, he was appointed Vice President. Seven months later, he was tasked with finding the traitor in Charleston. He was close to finding out who it was, and went to tell Tom. However, Anne had gone into labor and Tom had to leave before Arthur could tell him. He was murdered by Lourdes Delgado using Volm enhanced human weaponry. After his death, Marina Peralta became the new Vice President.
Arthur begins to track down who the traitor was in Charleston. While in his office, the traitor, Lourdes, who is controlled by Eye Worm's uses Volm enhanced human weaponry, and shoots him in the chest.
