MANILA: A Philippine senator who is an ally of Vice President Sara Duterte was arrested on Monday on a plunder charge, hours before the Senate begins a high-stakes impeachment trial that could determine Duterte’s political future.

Senator Rodante Marcoleta was due to sit as a senator-judge on Monday at the impeachment trial against Duterte.

If convicted by a two-thirds majority in the 24-member Senate, Duterte could be barred from running in the 2028 elections, where she remains the frontrunner to succeed ‌President Ferdinand ‌Marcos Jr.

In the Philippines, people charged with ‌plunder ⁠are not eligible for ⁠bail. It was unclear whether the charging of Marcoleta would affect the impeachment trial process.

The anti-graft court ordered Marcoleta’s arrest after the Ombudsman’s office had accused him of accepting 75 million pesos ($1.2 million) from private donors during his 2025 Senate run, violating anti-corruption laws.
