Senators Erwin Tulfo and Vicente Sotto III announced their intention to file legal complaints against 18 alleged former Marines and their lawyer, Levi Baligod, who have accused them of receiving kickbacks from flood control projects linked to former Ako Bicol Representative Zaldy Co. The senators confirmed their plans following a Senate hearing where the alleged former Marines claimed they delivered cash-filled suitcases to Tulfo's residence and to Sotto's assistant. Tulfo stated he would file charges for libel, while Sotto indicated a preference for cyberlibel, which he believes is easier to prove. Both senators have vehemently denied the allegations, suggesting that they are politically motivated to tarnish their reputations, especially with upcoming elections. Sotto mentioned that the accusations also involve his son, Quezon City Vice Mayor Gian Sotto, and his nephew, Pasig City Mayor Vico Sotto, indicating a broader political rivalry. The claims emerged during a Senate inquiry led by senators aligned with the opposition, challenging the current Senate leadership.
