MANILA - (UPDATED) Senator Antonio Trillanes IV has asked the Senate committee on banks, financial institutions and currencies to conduct an inquiry into the bank accounts of President Rodrigo Duterte and his daughter, Davao City Mayor Sara Duterte.

In Senate Resolution 602 filed Monday, Trillanes urged the committee to look into the possible violations of the Anti-Money Laundering Act by the Dutertes.

Trillanes cited bank documents in a VERA Files report showing the President and his daughter's wealth which were allegedly not fully disclosed in their Statements of Assets, Liabilities, and Net Worth.

The bank documents, he added, allegedly show their undisclosed transactions exceeding P500,000.

Senator Francis "Chiz" Escudero, banks committee chair, said the panel could only conduct an inquiry if the depositors would allow them to look into their bank accounts.

"Without it, we will always be hitting a wall because of the bank secrecy law similar to what we have been encountering in the case of Andy Bautista," he said.

Senate President Aquilino "Koko" Pimentel III, meanwhile, said Trillanes should file a corresponding case to the proper body if he thinks the evidence against the Dutertes is strong.

"Before, he tried it against Pulong (Paolo) Duterte and Mans Carpio. Now it's the same thing against other members of the Duterte family," noted Pimentel who is also president of PDP-Laban, the political party of Duterte

"If he really has the evidence, then he should bring an actual case in the proper body. Senate is not the body for that. We are part of legislative action," said the senator.

Senator Francis "Kiko" Pangilinan believes Duterte's accounts should be looked into but "whether the senate will step up is another issue," as the President has allies in the Senate.

Presidential spokesperson Harry Roque earlier described as "old news" Trillanes' call to investigate the bank accounts of the Dutertes. He said the government should not waste resources on this investigation.

Roque stressed that the documents that Trillanes used in his accusations are all unauthenticated.--with reports from Sherrie Ann Torres, ABS-CBN News
