This interview was taken before the elections but still has relevant information that will help you understand the political dynamics today.
After the May 2016 Philippine elections, word was that Senator Alan Peter Cayetano was groomed to be the next Senate President. Along the way however, Senator Koko Pimentel managed to grab the senate presidency from Senator Cayetano by negotiating with the other senators to support him instead of Senator Cayetano.
Although Senator Cayetano lost the senate presidency, many people felt that it was a blessing in disguise because of the way the senator was able to defend the president. If Senator Cayetano became the Senate President, he won't be able to defend the Duterte especially during the time Senator Leila De Lima and Senator Sonny Trillanes were on attack mode and were using Edgar Matobato to try to unseat President Rody Duterte.
One of the deals Senator Koko Pimental struck was with Senator Leila De Lima who was given the Chair of the Committee on Justice and Human Rights. Although she was eventually ousted upon the motion of Senator Manny Pacquiao to declare the chairmanship and membership of the Committee of Justice and Human Rights vacant, observers have noticed that Senator Koko Pimentel seemed to have a soft spot for De Lima.
This alleged special treatment earned the ire of radio personality Ben Tulfo. who slammed Pimentel for defending Sen. De Lima.
The interview shown above was given by Sandra Cam who exposed De Lima long before Duterte did. It is interesting to note that Sandra Cam links Pimentel to De Lima which makes Duterte supporters wonder where the loyalty of Senator Pimentel belongs.
