The Philippine Senate has lowered the minimum number of votes needed to convict Vice President Sara Duterte for impeachment. The Constitution requires two-thirds of all members of the Senate to convict an impeached official. The original slate of 24 senator judges meant a threshold of at least 16 was needed to convict. But only 20 judges can now vote, with two-thirds of that technically bringing the threshold down to 14. Jhesset Enano reports.
