Senator Vincente Sotto's speech initially made headlines of very different reasons.
He was speaking out against a bill promoting free birth control,
a divisive subject in this strictly Catholic country.
Sheeding tears, he said he believed that his baby son had died three decades ago
his wife had been pregnant while taking the contraceptive pill.
Pictures of his emotional address made the front pages of most newspapers.
But soon after Mr Sotto gave his speech, a pro-birth control researcher discovered that a large chunk of it,
the part where the senator gave evidence to back up his claim,
came from a blog called the Healthy Home Econemist.
The blogger, an American woman called Sarah Pope,who has no medical training,
says she doesn't agree with Senator Sotto's position and claims that he twisted her words.
The senator has responded to the growing online attacks against him by saying he's a victim of cyber-bullying.
