VP Duterte faces charges of corruption and threats amid a backdrop of political instability and the controversial return of an ICC-facing senator.

Philippines Senate Opens Impeachment Trial for Vice President Sara Duterte

MANILA – The Philippine Senate has commenced an impeachment trial against Vice President Sara Duterte, initiating a high-stakes legal process that could end her political career and further deepen the nation's political divisions. The proceedings began amidst a climate of turmoil, following a dramatic leadership change in the Senate and the recent reappearance of a senator wanted by the International Criminal Court (ICC).

The impeachment charges against Duterte include allegations of misuse of public funds, illicit wealth accumulation, and threats against prominent political figures, including President Ferdinand Marcos Jr. and First Lady Liza Araneta Marcos. In response, the Vice President, who has plans to run for president in 2028, has denied all accusations, asserting that the impeachment is politically motivated.

Senate President Alan Peter Cayetano formally announced the opening of the trial, stating that Duterte has 10 days to respond to the charges. The court has not yet set a date for the substantive hearings, leaving a period of uncertainty over the trial's progression.

Political Undercurrents and a Senator's Flight

The impeachment trial unfolds against a complex political backdrop. Just days before its commencement, the Senate saw a significant leadership shake-up, with Duterte loyalist Alan Peter Cayetano installed as the new Senate President. This shift was reportedly facilitated by Senator Ronald “Bato” dela Rosa, a key figure in former President Rodrigo Duterte’s contentious “war on drugs.”

Dela Rosa, himself facing potential international scrutiny over alleged crimes against humanity linked to the anti-drug campaign, had been in hiding following reports of an ICC arrest warrant. His unexpected reappearance to cast a decisive vote for Cayetano’s leadership was followed by a dramatic episode where he evaded law enforcement officers seeking to detain him. Subsequent reports of gunfire and a raid by soldiers added to the charged atmosphere surrounding the Senate.

The former president, Rodrigo Duterte, father of the current Vice President, is currently in the custody of the ICC in The Hague, awaiting confirmation of charges related to his administration's brutal anti-narcotics crackdown, which reportedly resulted in tens of thousands of deaths.

A Divided Nation Reacts

The political landscape in the Philippines remains fractured. The current President, Ferdinand Marcos Jr., and Vice President Sara Duterte ran on a joint ticket in 2022, representing powerful political dynasties. However, their alliance has since dissolved, leading to intense scrutiny of the Vice President’s financial dealings.

President Marcos Jr. has attempted to distance himself from the impeachment proceedings, characterizing them as a purely legislative matter. Meanwhile, external reactions highlight the deep divisions. Protesters gathered outside the heavily secured Senate building, with some rallying in support of Duterte and others demanding her conviction.

“The chaotic events of last week have clearly shown that the Senate, under the leadership of Duterte’s allies, will become an institution dedicated to protecting the interests of the Dutertes,” stated protest leader Mong Palatino. Conversely, others expressed a loss of faith in politicians, particularly following Dela Rosa's evasion of arrest. “Instead of seeking justice for victims of extrajudicial killings, you helped dela Rosa evade arrest,” lamented Manette Castillo, the mother of a drug war victim, directing her words towards the senators.

The outcome of Vice President Duterte's impeachment trial is anticipated to have significant ramifications for Philippine politics, potentially reshaping the 2028 presidential election landscape and influencing the nation's ongoing struggle with accountability and justice.
