MANILA – On-leave Technology Resource Center (TRC) director general Dennis Cunanan has arrived at the Senate to face the 9th Senate Blue Ribbon Committee hearing on the pork barrel scam. Cunanan has claimed that Senators Ramon Revilla Jr., Jinggoy Estrada, and Juan Ponce Enrile, through former chief of staff, Atty Gigi Reyes, funneled millions of their Priority Development Assistance Fund (PDAF) to bogus NGOs linked to Janet Lim Napoles, through the TRC as implementing agency. Cunanan, the latest to spill the beans on the pork barrel scam, has claimed that Senators Estrada and " Revilla "pressured" him via phone to release their pork barrel funds to fake non-government organizations (NGOs) set up by Janet Lim Napoles. He has also denied the senators' claims that their signatures in documents for the release of their PDAF were forged. He is under provisional coverage of the Department of Justice's (DOJ) Witness Protection Program (WPP) as the Ombudsman weighs in on his testimony. Three accused senators, all opposition figures, are expected not to attend the hearing.
