In 2011, WikiLeaks released a leaked 1994 diplomatic note from the US Embassy in Manila, recounting a private conversation between a diplomat and Joel de los Santos, a retired Filipino university professor who specialized in Islamic affairs. De los Santos alleged that Libyan leader Muammar al-Qaddafi had channeled $200,000 (5 million pesos) to Ramos' 1992 election campaign. Ramos dismissed the claim as "hearsay by itself, and is further based on a string of successive hearsay conversations" and challenged anyone who believed the claim to produce evidence.
