The National Bureau of Investigation (NBI) revealed that Vice President Sara Duterte and her ally, Princess Maui, failed to appear for a probe into alleged threats against her and her family.

Senior Agent Mark Calilung testified during Duterte's impeachment trial that the NBI invited both individuals to provide details about the supposed assassination plot, known as 'Oplan Romanov,' but they did not comply.The prosecution argued that Duterte's alleged threats against President Ferdinand Marcos Jr.and his family constitute high crimes and betrayal of public trust.

Defense counsel Mark Vinluan claimed the plot is real, asserting that Duterte's statements during a November 2024 press conference were driven by personal protection instincts.However, the NBI emphasized that without cooperation from the accused, investigations cannot proceed.The impeachment trial continues, with the Senate considering charges of culpable violation of the Constitution and other impeachable offenses.The case highlights tensions between political accountability and personal security claims in Philippine politics.
