The Senate majority and minority blocs are now composed of 11 members each following the voluntary surrender of Senator Jinggoy Estrada to authorities and the continued absence of Senator Ronald "Bato" dela Rosa, who remains at large in connection with a warrant of arrest issued by the International Criminal Court (ICC).

The Senate majority bloc retains Senate President Allan Peter Cayetano, Senator Loren Legarda, Senator Pia Cayetano, Senator Rodante Marcoleta, Senator Imee Marcos, Senator Joel Villanueva, Senator Chiz Escudero, Senators Mark and Camille Villar, Senator Robin Padilla, and Senator Bong Go.

The minority bloc is composed of Senator Tito Sotto III, Senator Panfilo Lacson, Senator Risa Hontiveros, Senator Sherwin Gatchalian, Senator Kiko Pangilinan, Senator Bam Aquino, Senators Erwin and Raffy Tulfo, Senator Lito Lapid, Senator Juan Miguel Zubiri, and Senator JV Ejercito.

With both blocs at equal numbers, concerns have been raised over a possible legislative gridlock that could prevent the Senate from conducting official business.

Some members of the Senate majority have previously pushed for a measure that would allow senators to vote through teleconferencing as a potential remedy to the impasse.
