The Senate impeachment trial of Vice President Sara Duterte resumed on July 22, 2026, with National Bureau of Investigation (NBI) Director Melvin Matibag returning to the witness stand for cross-examination under Article IV, which alleges grave threats against President Ferdinand Marcos Jr., his family, and former Speaker Martin Romualdez.

The trial faced delays as the defense requested more time to question Matibag, postponing the presentation of witnesses for Article I regarding alleged misuse of confidential funds.

The court issued subpoenas for additional witnesses, including former LandBank officials, amid ongoing debates over the credibility of evidence and procedural fairness.

Key moments included discussions on the NBI's investigation into the alleged threats, comparisons between Duterte's statements and those of her brother Sebastian Duterte, and senator-judges' critiques of procedural inconsistencies.The prosecution emphasized the gravity of the threats, while defense lawyers questioned the sufficiency of evidence and the legal processes involved.The trial remains a focal point of political discourse, with ongoing scrutiny of the impeachment proceedings' legitimacy and transparency.
