Senator John Osmeña is known as the ‘Lone Ranger’ for his independent mindedness and taking fearless stance despite overwhelming odds. He is a known graft-buster in the Senate. He has been a very vigorous opponent of the perceived extension of President Fidel V. Ramos’ term.

As graft-buster, Sen. Osmeña was behind the Senate investigations of many irregular and anomalous government transactions, including the so-called Petroscam, and those involving the Philippine Airlines and the Philippine Ports Authority, among others. His exposes have led to the resignation of corrupt government officials.
