House trial spokesperson Rep. Zia Alonto Adiong on Sunday challenged Vice President Sara Duterte to provide law enforcement agencies with evidence of alleged threats against her and her family, saying authorities cannot investigate claims that remain unsupported.

“If she feels threatened, she could have at least reached out and told the NBI (National Bureau of Investigation) or the police and given them something to work on, just to prove she feels threatened, so her side could be heard as well,” Adiong said in a radio interview.

Duterte has repeatedly said she does not feel safe and does not trust the police or courts, including during her appearance Saturday before the Quezon City Regional Trial Court after it issued an arrest warrant against her on three counts of grave threats.

“I do not feel safe, I really do not feel safe. I don’t trust the court, I don’t trust the police,” Duterte said. She later posted P360,000 bail, or P120,000 for each charge.

Duterte also accused the Marcos administration of surveillance and harassment after Interior Secretary Jonvic Remulla said authorities knew her whereabouts before enforcing the warrant.

“The statement of Secretary Jonvic Remulla appears to confirm the documents we have long held regarding harassment and surveillance operations of the Philippine National Police and other agencies of government against me,” Duterte said.

Remulla said authorities knew where Duterte was the night before but chose not to immediately enforce the warrant, citing respect for her position as vice president.

‘Intimidation’

Duterte questioned why authorities allegedly went to her mother and children despite knowing her location.

“And because you know where I am, one important question must be answered — why did you still have to go to my mother and my children?” she said.

“There is only one clear answer — to frighten and intimidate my family,” she added.

Adiong said he was not taking Duterte’s claims lightly and that anyone who feels threatened has the right to seek help. But he said the Vice President should provide evidence to allow authorities to investigate.

He said the NBI had reached out to Duterte since 2024 for details about threats against her, but she had yet to communicate with the agency.

Adiong also rejected Duterte’s claims of political harassment, saying the cases against her demonstrated that the law was being applied regardless of a person’s position.

“This is not political harassment because that’s what they’re trying to spin … it’s not even about her, it’s about the law being implemented equally to all citizens regardless of who you are,” he said.

The grave-threat case stems from Duterte’s 2024 remarks involving President Ferdinand Marcos Jr., First Lady Liza Araneta-Marcos and former House Speaker Martin Romualdez. The case also forms part of Article IV of her ongoing impeachment case.
