NBI chief: admission itself is betrayal of public trust
NBI Director Melvin Matibag, testifying as the prosecution's final witness for Article IV, stated that the Vice President's public admission that she had spoken to someone to kill President Marcos itself constitutes betrayal of public trust, and that the NBI's ongoing investigation is not needed to substantiate the impeachment case because the public admission already established it. The defense moved to strike the testimony as a conclusion of fact and law; the presiding officer denied the motion, ruling Matibag was qualified to give the interpretative answer.
Lascañas affidavit on Oplan Tokhang
Through NBI witness testimony, the prosecution introduced an affidavit — attributed to a former police officer and self-confessed member of the group known as the 'Davao Death Squad' — alleging that then–Davao City Mayor Sara Duterte was among the architects of, and was directly involved in, the anti-drug campaign known as Oplan Tokhang. The defense contested the affidavit's admissibility.
