Duterte, daughter of former president Rodrigo Duterte, was Marcos’ running mate in a presidential election that saw their ticket win in a landslide.
She remains his constitutional successor should he be unable to finish his six-year term.
But she is currently facing an investigation in the House of Representatives, led by Romualdez, over her alleged misuse of millions of dollars’ worth of government funds.
Both Romualdez and Duterte are widely expected to run for president in 2028.
Duterte stepped down as education secretary in June as relations between the two families reached a breaking point.
In October, the vice president said she felt “used” after teaming with Marcos for the 2022 poll.
Months earlier, her father had accused Marcos of being a “drug addict”, with the president the next day claiming his predecessor’s health was failing due to long-term use of the powerful opioid fentanyl.
The vice president told reporters on Tuesday: “I agree with the assumption that he (Marcos) is a drug addict”.
Neither have provided evidence for their allegations.
