Manny Pacquiao is part of a CNN documentary which, in part, reports on the fighting congressman’s being sought as a powerful advocate to assist the efforts of Cecilia Flores-Obanda of the Visayan Forum Foundation toward eliminating child prostitution in their native Philippines.

A congressman in the Sarangani Province who is considered perhaps the most famous Filipino in the country’s history, Pacquiao is shown visiting one of Obanda’s shelters for the abused children, where he spoke to a group of young girls.

“We are working very hard on a law to protect all of you against human trafficking. You can count on me to help,” said Pacquiao. “I know how you feel. Thanks very much for allowing me to be part of your get together… Thank you. I hope to see you all again sometime in the future.”

Once listed at No. 4 by Forbes.com among America’s Top 10 most influential athletes, Pacquiao actually met President Barack Obama and First Lady Michele Obama during a private White House luncheon with his wife, Jinkee, in February of 2011.

“He’s an idol of many people because of his story,” said Flores-Obanda of Pacquiao in the report, which chronicles the efforts by her Visayan Forum Foundation against child sex slavery.

“I hope that he realizes that this may be the hardest or the toughest fight that he would wage in his entire life, because this fight goes beyond 12 rounds.”

Near the end of Part II, Pacquiao delivers a compelling speech on behalf of Obanda’s cause.

“I bring to you the good news in our fight against human trafficking. I am happy to tell you…that slowly but surely, we have turned the tide…as a nation, we are locked and loaded in fighting human trafficking. During my visit to the Visayan Forum safe houses, I talked to children as young as nine years old who are trafficked for prostitution,” said Pacquiao.

“In 2008, my good friend, Cecila Obanda, was recognized as a modern day hero by the United States of America (for) the Visayan Forum’s pioneering work in providing assistance to victims. I believe that we can end human trafficking in our lifetime. That challenge for us is to make this impact sustainable. We have won the last the last few rounds, I think that it’s time to deliver the knockout punch. We need to be true to our words and actions. We need to send a clear message that Filipinos are not for sale.”

A crossover star who was born into poverty, a young Pacquiao left a family that could no longer afford to feed him and spent homeless nights sleeping outside and days scrounging for food.

And since being elected to congressional office in the Sarangani Province of the Philippines in May of 2010, and, again, last month, Pacquiao’s politics and his love for his countrymen have threatened to drag him into retirement and out of boxing, according to his trainer, Freddie Roach.

“If we’re talking experience, my experience is deep and wide. That’s one of the reasons why my heart goes out to helping the poor,” said Pacquiao, during the report.

“The people have a lot of difficulties. I feel their pain, how much they need, because I came from there. When they cry for help, I understand, because back in the day, I experienced worse.”

Pacquiao (54-5-2, 38 knockouts) has a welterweight fight with once-beaten junior welterweight contender Brandon Rios (31-1-1, 23 KOs) on Nov. 23 in Macau (Nov. 24 in China).
