Former senator Antonio Trillanes IV on Friday alleged that a company owned by Manases Carpio, the husband of Vice President Sara Duterte, received more than P319 million from China-linked sources, while members of the Duterte family received millions of pesos in manager’s checks from a man he identified as a Davao drug lord.

The impeachment trial took an unexpected turn on Day 26, when the Senate heard four retired Supreme Court justices on a separate but potentially crucial question: whether the two-thirds vote required to convict Duterte should always mean 16 votes in the 24-member Senate.

On Thursday, the court named retired chief justices Artemio Panganiban, Reynato Puno and Hilario G. Davide Jr., and retired associate justice Adolfo Azcuna as amici curiae, or friends of the court, to advise it on whether the 16-vote requirement should be changed in light of the nonparticipation of four senator-judges.
