Navotas Rep. Toby Tiangco has challenged the Marcos administration to prove that its anti-corruption campaign applies to everyone and should also be impartial.
His comments come after Assistant Ombudsman Jose Dominic Clavano IV said that the Ombudsman's case against former speaker Martin Romualdez will be boosted by the testimonies of several individuals.
Among them are former public works secretary Manuel Bonoan, who could establish he circumstances surrounding the implementation of the flood control projects, as well as former bodyguards of resigned Ako Bicol Partylist Rep. Elizaldy Co whose statements are consistent with other evidence already gathered by investigators.
He also pointed to Romualdez as the alleged "mastermind" of the flood control controversy.
In a statement on Saturday, Tiangco said that the developments leave the administraiton with an opportunity to demonstrate that its campaign against corruption will spare no one, including administration allies.
"If the administration truly has nothing to do with these acts of corruption, then it should be even more determined to hold accountable its allies or even relatives who allegedly exploited their close ties to the administration to steal from the Filipino people," Tiangco said.
He added that those who orchestrated and masterminded the "biggest corruption scandal in our country's history" must be held accountable.
"Above all, the money stolen from the people must be recovered," Tiangco added.
In an earlier statement, Romualdez's spokesman, Elaine Atienza, said that there is no evidence linking the former speaker in the flood control mess.
"Despite numerous Senate and House inquiries and other official investigations, no former or incumbent Department of Public Works and Highways (DPWH) official has ever identified Romualdez as having participated in the planning, procurement, implementation, inspection, payment, or release of funds for any alleged ghost project," Atienza said.
