MANILA, June 3 - Philippine President Marcos Jr. called on the Senate to "get back to work," expressing disbelief on Wednesday that an impasse in the upper chamber has stalled urgent legislative duties ahead of a congressional break.

The Senate has been paralyzed by a widening divide between the majority and minority blocs after the latter called on Senate President Alan Peter Cayetano to resign. No plenary sessions have been held in the past two days after members of the majority skipped attendance.

Cayetano is a close ally of the Duterte family. Former president Rodrigo Duterte, Sara's father, is in ICC detention in The Hague and will face trial charged with crimes against humanity. Dela...
