The Office of the Ombudsman is intensifying its investigation into alleged irregularities in Philippine flood-control projects, moving to rely on the testimonies of eight self-described bagmen and former public works secretary Manuel Bonoan as it prepares a case against former House speaker Martin Romualdez. Assistant Ombudsman Mico Clavano said investigators found the accounts of eight out of 18 former bodyguards of ex-congressman Zaldy Co to be “consistent and categorical” in describing supposed cash deliveries linked to Romualdez and Co.

Clavano told reporters that the ombudsman’s team assessed both the narrative details and the demeanor of the witnesses in interviews, concluding that only eight of the 18 have testimonies potentially strong enough to be used in a case. He said the probe has been slowed by delays in the signing of affidavits, blaming the witnesses’ lawyer, Levito Baligod, for seeking extensions beyond an original June 20 target date. The affidavits are a key step in formalizing the bodyguards’ statements for use in any future court action.

Romualdez’s legal camp, however, has pushed back hard against the direction of the investigation. Spokesman Elaine Atienza said that despite multiple Senate and House inquiries and other official probes, no current or former Department of Public Works and Highways official has identified Romualdez as having any role in planning, procurement, implementation, inspection, payment or fund release for alleged ghost projects. Atienza argued that even Bonoan, who has been tapped as a state witness and was directly involved in department operations, had never previously implicated the former speaker, and she stressed that no single official, including the House leader, controls the national budget process, which is drafted by the executive branch through the Department of Budget and Management and implementing agencies.

Defense lawyers, including Atienza and Ade Fajardo, suggested that the move to place Bonoan under the Witness Protection Program may indicate a lack of concrete evidence tying Romualdez to any anomalous flood-control contracts, warning that their client risks becoming a political scapegoat. The high-profile probe has also prompted political ripples within the administration coalition: Navotas Representative Toby Tiangco publicly challenged the Marcos government to prove that its anti-corruption campaign is impartial and will “spare no one,” including allies and relatives accused of exploiting close ties to those in power. Tiangco said those behind what he called the “biggest corruption scandal in our country's history” should be held to account and that any public funds proven to have been stolen must be recovered, framing the case as a test of the administration’s resolve to pursue graft cases even when they reach into its own ranks.
