House Secretary-General Reginald S. Velasco did not identify who will file the complaint nor the congressman who will endorse the complaint, but said a lawmaker from the House majority caucus floated the possibility of filing ouster charges against the embattled vice-president. “They haven’t said how many will endorse it yet. They just said to wait for the fourth complaint,” he said in a phone interview with reporters in Filipino. “It was given to me in confidence. So, I cannot reveal their names until they actually file the fourth complaint.”
