Presidential son and Davao City Vice Mayor Paolo Duterte on Thursday said an "ugok" senator is "throwing wild accusations" against him and his father, President Rodrigo Duterte.

The younger Duterte, in a statement, said that if he indeed has millions in his bank account, he will give them to the victims of the Surigao earthquake.

"If this senator, whose name is not worth mentioning, could prove that I have those millions in the said bank accounts, then I will give them all to the victims of the earthquake in Surigao," he said.

He said the lawmaker earlier accused him of being a drug user.

"From drug test and now bank test. If I may suggest for him to take a psychiatric test as something is very very wrong with his mind," he said.

In a press conference Thursday, Senator Antonio Trillanes released documents on President Rodrigo Duterte's alleged bank transactions and supposed records of his 3 children's bank accounts.

Trillanes renewed his challenge for President Duterte to prove him wrong by baring the history of his bank transactions.

Meanwhile, Paolo Duterte called for the senator's resignation, and told the senator to "rot in hell."

"Kung gusto mo magresign Senator Ugok, magresign ka na. Huwag ka na madami pang dahilan. You are a useless senator and the people of the Philippines no longer believe you," he said.

"You can rot in hell for all we care!"
