"No such directive exists nor has been made. Deepfakes are an advanced form of digital content manipulation through the use of generative Artificial Intelligence," the PCO said.

The PCO said they are actively working on measures to combat fake news, misinformation, disinformation, and malinformation.

"We are also closely coordinating and working with the DICT, the National Security Council, the National Cybersecurity Inter-Agency Committee (NCIAC), and relevant private sector stakeholders to actively address the proliferation and malicious use of video and audio deepfakes and other generative A.I. content," the office said.

Earlier, PCO Undersecretary Emerald Ridao said “9 out 10” people are vulnerable to "fake news."
