Center of the storm

Manny Villar is once again at the center of the storm. The C-5 fiasco seems to be hounding him to no end as senators throw bricks and stones at each other over their report. Political supporters are at each others throat saying that everything is politically motivated, the timing is in question, why only now? Those kind of BS.
Villar's camp keeps on insisting there was no insertion of anything, while his critics disagrees.
Things get hairy when Villar refused to attend the senate committee of the whole to discuss this matter. IMO, he should just attend since it's not really a trial. Media is making a frenzy over this.
My question is who will gain from this? Will it help the Filipino people in anything?
