As Senator from 1987 to 1992, Laurel opposed the extension of the U.S. Naval Base Subic Bay and the Clark Air Base, leading to their closure in 1991. He was a member of the so-called "Magnificent 12" who voted against the extension. He was also the Chairman of the Senate Committee on Commerce and Industry and was the Senate President Pro-Tempore from 1990 to 1991. He was the oldest serving senator also at that time.
