Politics can beat the plot of most films at times.
Reality could be stranger than fiction. Politicians could be more loose than the presumably more notorious artistas. When the President divulged that a lady senator had her married driver as a lover, he definitely wasn't abusing his power as she claimed but doing a great service to the nation. A politician's private life has a great bearing on a politician's official acts. A big question mark emerged as to the senator's judgement & integrity, thus her credibility. Has her bedroom secrets compromised her already to foreign intelligence agencies & powers? The apparent "poor" judgement of West German leader Angela Merkel in her presumably anti-German policies with regards to the refugee problems is attributed by certain quarters to her being compromised by foreign powers for some supposedly "blackmailable" secrets. Blackmailable secrets are usually the reason for baffling official acts of politicians with apparently poor judgement in their personal lives.
While noisily protesting about alleged human rights violations despite the popularity of the Duterte anti-drug campaign, was Senator de Lima actually at the end of a string pulled from somewhere else?
They should pursue this case. If there is a video, they should release it online (it will be interesting not for its prurient value). And if it turns out to be true, Senator de Lima should resign.
