Here are the senators who didn't sign the pro-Zubiri resolution
By Dhel Nazario
While some senators have affirmed their support for the leadership of Senate President Juan Miguel “Migz” Zubiri amid rumors of replacement, some have yet to sign the resolution or statement of support for him.

At least 14 signatures of senators are needed to stabilize Zubiri’s leadership. So far, 14 senators, have confirmed support for him.
In a statement, Zubiri said that he is "deeply humbled" by his colleagues’ continued trust in his leadership of the Senate.
"I always say that I serve at the pleasure of my colleagues, and with their strong show of support, I am emboldened to press on as Senate President," he added.
Zubiri thanked his fellow Senators who already signed the statement of support, as well as those who have signified intent to sign it as well.
"Ang suporta nilang lahat ay marka ng isang matatag na Senado, hindi natitinag ng anumang ingay, at palaging nagkakaisa sa aming paglilingkod sa bayan (Their support is mark of a strong Senate, not swayed by any noise, and always uniting to serve the country)," he said.
This, after rumors buzzed of Zubiri being replaced by another senior lawmaker in the Upper House—in particular, Sen. Jinggoy Ejercito Estrada.
However, Estrada, his brother Joseph Victor “JV” Ejercito, Ramon “Bong” Revilla, Jr. also signified their intention to sign the resolution supporting Zubiri’s leadership.
Others are Senators Sherwin Gatchalian, Sonny Angara, Grace Poe, Nancy Binay, Manuel "Lito" Lapid, Raffy Tulfo, Mark Villar, Ronald "Bato" Dela Rosa, Francis Tolentino, and Christopher "Bong" Go.
Zubiri also signed the resolution.
As of writing, those who have yet to sign are Senate Majority Leader Joel Villanueva, Senators Imee Marcos, Cynthia Villar, Alan Peter Cayetano, Pia Cayetano, Robin Padilla, and Loren Legarda and Francis "Chiz" Escudero.
Escudero is still overseas.
Meanwhile, Senate Minority Leader Aquilino "Koko" Pimentel III and Sen. Risa Hontiveros are members of the minority bloc.
Marcos confirmed there were rumors of a plot to oust Zubiri as leader but the issue emanated from outside of the Senate.
Marcos pointed to the leaders of the House of Representatives, which has been pushing for Charter change through a People’s Initiative, but later on filed their own version of a resolution seeking economic amendments to the 1987 Constitution.
At the same time, Marcos expressed doubts any plot to oust Zubiri at this time would materialize.
In a separate message, Ejercito said he will join the minority bloc should there be a change in the Senate leadership.
