MANILA - The camp of Vice President Leni Robredo on Tuesday said it was planning to file criminal charges against a blogger who alleged that the vice president slept around during a trip to South Africa last year.

Videos of blogger Drew Olivar spewing expletives and sexual allegations against Robredo were uploaded on Twitter shortly after the blogger drew flak for alluding to female genitals while discussing federalism with Assistant Communications Sec. Margaux "Mocha" Uson.

"Our legal team is currently looking into the possibility of filing a criminal complaint. Do stay tuned," said Robredo's spokesperson Barry Gutierrez in a tweet.

In the series of videos, Olivar was seen holding the camera while ranting and making serious claims against Robredo.

"Forty-eight years ka nang nandiyan sa South Africa wala ka pa rin dito. Puro photo op ka parati diyan put*** i** mo," Olivar said pertaining to Robredo's 2017 visit to South Africa where she delivered a keynote address in a women's forum.

"Pasiklab ka na naman na parang mabait ka na naman na parang tumutulong ka e nandiyan ka lang naman nagpapakan***," he said.

"Kahit naririnig ng mga tao wala [akong] pakialam kahit public scandal ito e totoo naman na nagpapakan*** ka lang naman diyan sa South Africa," he added.

In another video, Olivar also slammed Roberdo for sending one of her daughters to study in Harvard University.

"'Yang anak mo, mag-aaral sa Harvard P150,000 or P200,000 ang lifestyle tapos wala namang gagawin sa bayan," the blogger said.

Last year, Robredo's eldest daughter Aika has been accepted into the Master's Degree programs in Harvard University in Cambridge, Massachusetts, USA and in the University of Oxford in Oxford, England.

Robredo said her daughter had applied for a scholarship.
