LIVE UPDATES: Sara Duterte impeachment trial | Sept. 28, 2026

MANILA, Philippines – Davao City Mayor Sebastian “Baste” Duterte may take the witness stand on Monday as the House prosecution panel seeks to establish the alleged unexplained wealth of his sister, Vice President Sara Duterte, on the 30th day of her impeachment trial.
- Mayor Duterte is expected to testify after the cross-examination of Philippine Government Electronic Procurement System (PhilGEPS) Electronic Government Procurement Operations Division chief Rendell Sopeña.
- The House prosecution completed its direct examination of Sopeña last week where he testified that 49 food service contracts worth a combined P35 million were awarded by government offices in the Davao Region to Gencorp Industries Inc. during the terms of the Duterte siblings.
- Gencorp, formerly known as Timesquare Bee Foods Corp., has been declared as one of Vice President Duterte’s business interests in her statements of assets, liabilities and net worth (SALNs) from 2016 to 2025.
- The contracts prompted the House prosecution to seek Mayor Duterte’s testimony on the city government’s dealings with Gencorp. /dp
