Priority Development Assistance Fund (PDAF) scam

The Priority Development Assistance Fund scam, also called the PDAF scam or the pork barrel scam, is a political scandal involving the alleged misuse by several members of the Congress of the Philippines of their Priority Development Assistance Fund (PDAF, popularly called "pork barrel"), a lump-sum discretionary fund granted to each member of Congress for spending on priority development projects of the Philippine government, mostly on the local level.

The scam was first exposed in the Philippine Daily Inquirer on July 12, 2013, with the six-part exposé of the Inquirer on the scam pointing to businesswoman Janet Lim-Napoles as the scam's mastermind after Benhur K. Luy, her second cousin and former personal assistant, was rescued by agents of the National Bureau of Investigation on March 22, 2013, four months after he was detained by Napoles at her unit at the Pacific Plaza Towers in Fort Bonifacio. Initially centering on Napoles' involvement in the 2004 Fertilizer Fund scam, the government investigation on Luy's testimony has since expanded to cover Napoles' involvement in a wider scam involving the misuse of PDAF funds from 2003 to 2013.
