He said over the weekend that Trillanes, his political foe, has been trying to undermine him and his family with baseless allegations, calling the senator a "political ISIS" who aims to destroy him but could not offer any shred of evidence.
"Once and for all, I now have the time to deny any and all baseless allegations thrown against me", Paolo Duterte told the Senate.
Carpio, the husband of Sara Duterte, now the Davao city mayor, said he and his brother-in-law "have been publicly crucified based on rumors and gossips".
"But one BOC employees showed me a text message from a certain Mans asking help for the lifting of the alert order on the said 60 containers of Gamboa which we declined", Anderson said, adding: "But no Atty".
"We have been publicly crucified based on gossip", Duterte said.
Denying that he had met Taguba, Carpio said he is a lawyer by profession "and my practice involves representing my clients in courts and other government institutions including the BOC". "In fact, the case I'm working on in the BoC dates back to the administration of former President [Benigno] Aquino [3rd]", Carpio said.
Carpio said he never met customs broker Mark Taguba and can not say anything about his claims regarding the alleged Davao group facilitating cargoes of alleged smugglers.
Sen. Antonio Trillanes IV insisted on their attendance, saying he would let the public judge them.
He claimed the young Duterte has a dragon-like tattoo with secret digits on his back that is the mark of a triad gang member. Panfilo Lacson in his privilege speech as a member of the Davao Group; and Davao City Councilor Nilo Abellera, who was also named by Taguba as part of the Davao Group. The crime group has been linked to human trafficking and arms dealing. Last week, Taguba issued a statement attempting to clear the pair of any involvement in illegal drugs or anomalies at customs.
"I don't think so. They are just saying that", Taguba said when asked by Sen.
Duterte and Carpio were summoned by Sen.
The president's son-in-law, Manases Carpio, who has also been accused of links to the May drug shipment from China, told the hearing he had no involvement.
"Itong intelligence information na ito ay binigay sakin ng isang foreign country na sinasabi ay itong si Vice Mayor Paolo Duterte ay member ng triad".
Paolo Duterte acknowledged he has a tattoo during questioning but refused to show it, citing his right to privacy.
Asked by Trillanes if he would allow a photograph to be taken of the tattoo and sent to the US Drug Enforcement Agency to decode secret digits, Duterte said: "No way".
During the hearing, Trillanes challenged both Carpio and Duterte to sign a waiver on several bank accounts which the senator said was owned by them.
At this point, Senator Richard Gordon, chairman of the Blue Ribbon committee, cautioned against making "allegations without any basis".
"That's pretty drastic", said Abella about the senator's allegations.
Trillanes claimed he had information that Duterte had over PHP100 million in at least two bank accounts - the Rizal Commercial Banking Corporation and the Bank of the Philippine Islands in Davao City.
Senate Majority Leader Vicente Sotto III then asked Trillanes to focus on the subject of the investigation which is the "tara system" at the BOC and the shabu shipment.
Lawyer Rainier Madrid, counsel of Duterte, described Trillanes as a "propagandist" and a "manipulator".
"That is Trillanes' propaganda".
Asked if he had seen the vice mayor's tattoo, Madrid said: "I have not seen it because I'm not gay".
During the hearing, Trillanes presented photos taken from social media of Dong and the younger Duterte together to point out their links.
