Senate President Alan Peter Cayetano accused the National Bureau of Investigation (NBI) chief of telling lies during a press conference on May 14, 2026 [1].

The public clash between the legislative leader and the head of the country's premier investigative agency suggests a significant rift in the Philippine government's internal coordination. Such disputes can impact the perceived integrity of official investigations and the stability of executive-legislative relations.

Cayetano spoke to reporters at the Senate building in Manila [1]. He said that the NBI chief had made false statements, though the specific nature of the alleged lies was not detailed in the immediate briefing. The confrontation highlights growing tensions regarding the accuracy of information being provided by the bureau to the Senate.

During the conference, Cayetano directed a sharp critique toward the NBI chief. "Ayusin niya muna sarili niya!" Cayetano said [1]. This phrase, which translates to a demand for the official to fix his own affairs first, indicates a personal and professional breakdown in trust between the two officials.

The NBI chief has not yet issued a formal response to these specific accusations. The Senate building serves as the backdrop for this escalating dispute, where legislative oversight often clashes with the operational secrecy of investigative bodies. This event marks a public escalation in a conflict that had previously remained behind closed doors.

Because the NBI is responsible for critical national security and criminal investigations, accusations of dishonesty at the top level can lead to calls for leadership changes or formal inquiries. Cayetano's decision to bring these claims to a press conference on May 14, 2026 [1], ensures that the matter will remain under public scrutiny.

"Ayusin niya muna sarili niya!"

This public confrontation signals a breakdown in the working relationship between the Philippine Senate and the National Bureau of Investigation. When the Senate President openly accuses a top law enforcement official of lying, it often precedes formal legislative inquiries or administrative shake-ups, potentially undermining the credibility of ongoing NBI investigations.
