Lawyer Harry Roque believes that Vice President Sara Duterte is not the cause of the 'rift' between the Marcoses and Dutertes.

The claim was made after former President Rodrigo Duterte, on Sunday evening, Jan. 28, accused President Ferdinand Marcos Jr. of being a "drug addict," citing PDEA's alleged watch list.

Davao City Mayor Baste Duterte also urged Marcos to resign from his post during his speech at the Maisug Leaders Forum in Davao City.

Interviewed in DZRH's Dos Por Dos on Monday, Roque said that the heat between the two was probably due to the statement made by Justice Secretary Boying Remulla that the government had already contacted the International Criminal Court (ICC) to investigate Duterte leadership's bloody war on drugs campaign.

"Tingin ko, ang pinaka-importanteng nangyari ay yung nagsalita si Justice Sec. Remulla na matapos sabihin ng Pres. na 7 buwan nang nakakausap na hindi na makikipag-ugnayan sa ICC," Roque said.

"Nagsalita si Justice Sec. Remulla na makikipagtulungan na. Ang dahilan niya ay mayroong mga resolution ang Kamara. Tingin ko, binasa ng mga Duterte 'yan na declaration of war," he added.

According to Roque, the events that happened only showed that the "Uniteam" has officially ended.

"Kung ang mga pangyayari kagabi ay patunay na talagang natapos na ang Uniteam, 'yon ay dahil sa banta na kakaladkarin ng dating Presidente, posible si VP Sara, at makikipagtulungan ang gobyernong Marcos," he said.

In the talks of the former president's statement, Roque said he also saw PDEA's watchlist containing Marco's name, which he questioned why the agency denied it.

"Sa tingin ko, hindi siya [FPRRD] magsasalita ng ganoon na walang basehan. Ako mismo, nakita ko ang listahan ng PDEA. May mga kumakalat naman talagang report," he said.

"May nakita ako [listahan ng PDEA]. Hindi siya mahabang watchlist. Ito kumbaga ay memo na may 3 personalinad na namomonitor na gumagamit. Kung di ako nagkakamali, 2012 ang petsa," he furthered.

Roque believes that if the accusation were true, the country would be put in danger.

Responding to the "drug addict" accusations, Marcos just laughed, saying the former president's behavior was due to his taking fentanyl drug for "a very long time."

"PRRD has been taking the drug for a very long time now. When was the last time he told us he was taking fentanyl, mga 5 or 6 years ago? After 5 or 6 years, it has affected him kaya palagay ko nagkakaganyan. I hope his doctors better take care of him," the Chief Executive said.
