Zuleika Lopez arrives at Senate on Day 5 of impeachment trial

Office of the Vice President (OVP) chief of staff Zuleika Lopez, the longtime aide of Vice President Sara Duterte, arrived at the Senate on Tuesday, the fifth day of the impeachment trial of the country's second highest official.

Lopez came at the Senate past 1 p.m. ahead of the resumption of the trial at 2 p.m.

She went straight to the Recto room, the holding area for the defense panel.

It is still uncertain if Duterte will also go to the Senate on Tuesday to attend the trial or to visit her team.

She is set to be presented by the House prosecution panel as its third witness in the trial in connection with the Article 4 of the Articles of Impeachment, relating to the supposed grave threats and assassination plot against President Ferdinand "Bongbong" Marcos Jr., First Lady Liza Araneta-Marcos, and former Speaker Martin Romualdez.

The Senate, sitting as an impeachment court, earlier issued a subpoena ad testificandum to Lopez upon the request of the prosecution team.

Lopez also went to the Senate on July 9—a non-trial date and a day after the issuance of the subpoena—to visit the office of Senate Secretary and Clerk of Court Renato Bantug Jr. for what were described as "mainly administrative" matters. — VDV, GMA News
