Metro Manila (CNN Philippines, October 15) — Defeated presidential candidate Manuel "Mar" Roxas II on Monday announced that he is gunning for a Senate seat in the 2019 midterm elections.

Roxas, a former Interior Secretary and Senator, confirmed the development to CNN Philippines in a text message on Monday.

The former Cabinet secretary, who was defeated by then Davao Mayor Rodrigo Duterte in the 2016 presidential race, fueled speculations of his planned return to politics when he posted a video on his official Facebook page.

In the four-minute clip, Roxas said that his "love for the country" and a desire to help his countrymen helped formalize his decision.

"I'm not perfect, I made mistakes. May mga pagkukulang. Pero masasabi ko, buong buo kong binigay ang sarili ko sa bansa at sa kapwa." Roxas said in the video.

[Translation: I'm not perfect, I made mistakes. I have shortcomings, but I can say I can wholeheartedly give myself to the country and to my countrymen.]

"Mahal ko ba ang bansa natin? Oo. May maitutulong ba ako? Oo. Apart from disappointment, may dahilan ba na ipagkait ko ang tulong ko sa mga nangangailangan? Apart from pride, may dahilan ba na hindi ako mag-extend ng helping hand? Wala. And so here we are."

[Translation: Do I love our country? Yes. Can I help? Yes. Apart from disappointment, do I have a reason not to help those in need? Apart from pride, do I have a reason not to extend a helping hand? None. And so here we are.]

"I don't have any quit in me, and I won't quit on our country," he added.

Roxas, however, did not specify which post he was aiming for in the video.
