DAVAO CITY — Vice President Sara Duterte on Tuesday pressed the National Bureau of Investigation to release video documentation of dismissed policeman Rodulfo Gracioso Jr.'s polygraph examination, saying transparency is necessary to resolve questions about the test's authenticity.

Duterte emphasized that making the examination footage public would help dispel widespread doubts regarding whether the procedure actually took place. The Vice President indicated she harbors no reservations about submitting herself to a similar polygraph test if required.

The demand underscores mounting scrutiny surrounding the polygraph examination and its role in an ongoing investigation. By calling for public disclosure of the test materials, Duterte has signaled her administration's stance on government transparency in high-profile cases.

Gracioso's status as a dismissed officer and the examination's connection to a broader investigation have drawn considerable public attention, making the release of supporting documentation a matter of public interest.
