He sees no action vs VP Sarah Duterte. He advised Usec Andres to shut up and said that his office can alone stop VP. It is within the power of the Ombudsman to take over the VPs investigation.
We also do not agree that VP Sarah can only be impeached and then only can be charged criminally afterwards when she has lost her immunity.
VP Sarah has probably found a white knight in Martires whom his father appointed as Ombudsman
