In a significant development regarding the flood control investigation in the Philippines, Senator Erwin Tulfo has invited 18 individuals claiming to be former Marines to participate in a Senate blue ribbon committee hearing. These individuals allege they served as 'bagmen' for former congressman Zaldy Co, implicating several officials in corruption, including Tulfo himself. The hearing is set for June 8, following a previous session led by Senators Pia Cayetano and Rodante Marcoleta, who are part of a bloc contesting Tulfo's chairmanship of the committee. The alleged ex-Marines have been asked to provide notarized affidavits detailing their claims and have previously accused various officials of receiving funds from Co. However, both Tulfo and Senator Vicente Sotto III have refuted these allegations, asserting their innocence in the matter. This hearing marks a continuation of the Senate's scrutiny into the flood control mess and the alleged corruption surrounding it.
