MANILA, Philippines — The chief of staff of the Office of the Vice President (OVP), Undersecretary Zuleika Lopez, and confidential payment recipient Mary Grace Piattos were among the 57 witnesses listed by the prosecution panel for Vice President Sara Duterte’s impeachment trial.

Copies of the prosecution’s pre-trial brief shared by sources with reporters on Thursday showed that for Article I of the Articles of Impeachment, or the allegations of confidential fund (CF) misuse, the prosecution listed 27 witnesses, including Lopez and Piattos.

The prosecution said Lopez will be asked to take the witness stand to “prove that respondent misused and misappropriated confidential funds,” while Piattos will be asked to “testify on their alleged receipt of confidential funds.”
