Vice President Sara Duterte’s Impeachment Trial Begins Amid Senate Turmoil
5/18/2026, 11:07:27 PM
Opening of the Impeachment Court
On May 18 2026 the Philippine Senate sat as an impeachment court and formally opened the trial of Vice President Sara Duterte. The Senate’s new president, Alan Peter Cayetano, declared, “The trial of Vice President Sara Zimmerman Duterte is hereby open.” Duterte, 47, faces a ban from holding public office if convicted, a result that could end her bid for the 2028 presidency.
Background and Political Context
The trial follows a series of destabilising events: a shoot-out in the upper house, a rapid change in Senate leadership, and the dramatic return of Senator Ronald “Bato” dela Rosa, a pro-Duterte figure wanted by the International Criminal Court (ICC) for alleged crimes against humanity linked to the former president’s drug war. Duterte’s father, ex-President Rodrigo Duterte, is awaiting his own ICC trial. President Ferdinand Marcos Jr., barred from running again, has publicly distanced himself, describing the impeachment as a legislative matter. The fallout between Marcos and Duterte has intensified scrutiny of the vice-president’s finances.

Official Statements & Responses
Cayetano’s opening remark signalled the court’s commencement. President Marcos reiterated that the matter is legislative, while the administration confirmed plans to arrest dela Rosa. The solicitor-general rejected dela Rosa’s bid for a Supreme Court injunction blocking his arrest, stating no legal basis exists for a foreign warrant.
Criticism & Opposition
Protest leader Mong Palatino warned that the Senate, under Duterte allies, may become an institution protecting the Dutertes. Manette Castillo, a drug-war victim’s mother, accused senators of shielding Duterte and enabling dela Rosa’s evasion.
On-the-Ground Reports
Dozens gathered outside the heavily guarded Senate building, with demonstrators split between support for Duterte and calls for her conviction.
Conflicting Reports & Gaps
Sources differ on dela Rosa’s current location; his whereabouts remain unconfirmed. The trial’s schedule beyond the opening remains unspecified, leaving the timeline for hearings unclear.
