The House prosecution panel on Tuesday asked the Senate impeachment court to allow it to present Office of the Vice President (OVP) chief of staff Zuleika Lopez and National Bureau of Investigation (NBI) Director Melvin Matibag as witnesses in the impeachment trial of Vice President Sara Duterte.
The prosecution panel requested the issuance of subpoenas ad testificandum directing Lopez and Matibag to appear and testify before the impeachment court on July 13 to 15, 2026 at 2 p.m.
Tagged as “witnesses,” the prosecution said that the two’s testimonies are “material, relevant, and necessary to establish the allegations” under Article IV of the Articles of Impeachment against Duterte.
Article IV centers on the alleged grave threats and an assassination plot by the Vice President against President Ferdinand “Bongbong” Marcos Jr., First Lady Liza Araneta-Marcos, and former Speaker Martin Romualdez.
