MANILA – The National Bureau of Investigation’s (NBI) full investigation into Vice President Sara Duterte’s alleged “continuing threat” against President Ferdinand R. Marcos Jr. will be presented before the Senate impeachment court next week, a House prosecutor said Friday.

Bicol Saro Party-list Rep. Terry Ridon said NBI Director Melvin Matibag is scheduled to testify on July 21 as the prosecution’s final witness for the fourth article of impeachment, which centers on Duterte’s alleged threats against the President and his family.

The fourth article of impeachment accuses Duterte of betrayal of public trust and other impeachable offenses over her Nov. 23, 2024 statement that she had contracted an assassin to kill President Marcos, First Lady Liza Araneta-Marcos, and then-Speaker Ferdinand Martin G. Romualdez should she herself be killed.

“Sa darating pong Martes, si NBI Director Melvin Matibag ang huli pong isasalang ng prosekusyon para sa article on threats para tahiin ang kabuuan ng naging imbestigasyon ng NBI dito sa continuing threat ng Pangalawang Pangulo laban sa ating Pangulo at sa kanyang pamilya,” Ridon said during a press briefing.

Ridon said Matibag would present the NBI’s “full Bureau reporting,” which includes more than the digital forensic evidence and investigative findings previously presented before the impeachment court.

“Hindi lang po ito cybercrime investigation katulad ng ginawa ni Atty. Lotoc at ni Agent Calilung, kundi ang iba pang mga ulat mula sa kabuuan ng opisina ng NBI,” added Ridon, who chairs the House Committee on Public Accounts.

The prosecution has so far presented NBI Special Agent John Mark Calilung, who authenticated the Nov. 23, 2024 video containing Duterte’s statements, and NBI Regional Director Jeremy Lotoc, who testified that the bureau’s investigation led to its recommendation to file three counts of grave threats and one count of inciting to sedition against the Vice President.

Former Surigao del Norte Rep. Robert Ace Barbers, adviser and spokesperson for the House prosecution panel, said the prosecution’s case remains intact after the defense’s cross-examination of its first two witnesses.

“Nakita naman natin sa dalawang testimonya ng aming mga witnesses… hindi pa ho nagigiba ’yung credibility ng aming mga testigo,” Barbers said.

He also noted that the defense used the same authenticated video presented by the prosecution during its cross-examination of Calilung.

“Itong ebidensyang in-authenticate ng aming unang witness ay in-authenticate din naman ng panig ng depensa dahil kitang-kita na ginamit din nila itong ebidensyang ito,” Barbers said.

Barbers likewise cited Lotoc’s testimony that the NBI found sufficient basis to recommend filing three counts of grave threats and one count of inciting to sedition against Duterte.

Following Matibag’s testimony, the House prosecution is expected to conclude its presentation of evidence on the impeachment article involving Duterte’s alleged threats before proceeding to the article on the alleged misuse of confidential funds.
