The Senate impeachment court subpoenas Zuleika Lopez, the chief of staff of the Office of the Vice President, for the impeachment trial of Vice President Sara Duterte. Court spokesperson Reginald Tongol confirms that the House prosecution panel requested a subpoena ad testificandum for Lopez, and the presiding officer grants the request. She is ordered to appear and testify as one of the prosecution’s key witnesses. Reporting indicates the subpoena is issued on Wednesday and that Lopez is expected to be presented by the House prosecution panel when hearings resume later, with the court setting her testimony for the next phase of proceedings after the first week ends. The subpoena is connected to the prosecution’s plan to call multiple witnesses in the subsequent hearings to support the impeachment case, including the grave-threats allegation under Article IV. The sources agree the action is part of the court’s process to secure witness testimony for the impeachment trial. No alternative witness or timing changes are cited across the reports.
