MANILA, Philippines — Sen. Ronald Dela Rosa said on Wednesday that he would not attend the hearing by the House of Representatives on the war on drugs under his former boss, then president Rodrigo Duterte, even as he has yet to receive an invitation from the committee that would take on the inquiry.

This developed after the House Committee on Human Rights approved the day before a motion by Gabriela Party-list Rep. Arlene Brosas to invite the former leader, ex-senator Leila de Lima, and Dela Rosa. The committee's decision was based on their roles and involvement in the war on drugs.
