Ronald Quantrell was an Earth Alliance Senator. As of 2259, he was chairman of the Babylon 5 Senate Oversight Committee. He was a staunch humanocentrist and was hesitant to support the Babylon Project. Even so, he felt that Earth owed it to late-President Luis Santiago's memory to continue operating Babylon 5. He claimed that the Earth Alliance, after rebuilding its defenses, was now capable of going toe-to-toe with the Minbari, even hinting that Earth would now win with their new ships and weapons.
