MANILA — Ex-Senator Antonio Trillanes IV showed up at the Senate chamber Tuesday to observe the impeachment trial of Vice President Sara Duterte, marking his involvement in the high-profile proceedings as both spectator and prosecution witness.

Trillanes, who served in the Senate until 2022, was spotted alongside members of the House prosecution panel attending the day's hearings. His presence underscores the political significance of the impeachment case, which centers on allegations of unexplained wealth against the Vice President.

The former legislator's dual role—as an observer and listed witness for the prosecution—indicates his expected participation in forthcoming testimony. The House prosecution panel continues to present its case against Duterte, with witness testimony set to play a central role in proceedings.

The impeachment trial represents one of the most consequential political developments in recent months, drawing prominent figures from across the political spectrum to the Senate.
