Senators have one by one come out with statements insisting that the chamber vote separately from the House of Representatives should Congress convene as a Constituent Assembly in order to amend or revise the 1987 Constitution. At the same time, some of them have questioned whether changing the law of the land will solve the nation's problems, or if it is needed at all.
