The National Bureau of Investigation (NBI) testified during Vice President Sara Duterte's impeachment trial that no relevant threats were found against her life.

NBI Bangsamoro chief Jeremy Lotoc stated that while the removal of 75 personnel from the VPSPG was noted, there was no validated information confirming threats.

The defense argued that the NBI's investigation into threats against Duterte was biased, citing discrepancies in the probe compared to cases involving President Ferdinand Marcos Jr.Lotoc clarified that the term 'Operation Romanov' was first used by Davao City Mayor Baste Duterte in 2024, not Duterte.The defense emphasized the importance of addressing potential bias in the investigation, as it could affect the trial's outcome.The case revolves around the fourth article of impeachment, which alleges grave threats against the Marcos couple.

Despite the NBI's findings, the defense maintains that Duterte's actions were a reaction to perceived threats, highlighting the complexity of the legal and political implications.
