MANILA -- Communications Assistant Secretary Margaux "Mocha" Uson said Wednesday she was resigning from her post to aid the passage of her agency's budget, but warned critics that her fight was not yet over.

The House of Representatives had deferred action on the budget of the Presidential Communications Operations Office after Uson failed to attend budget deliberations.

She told a separate budget hearing at the Senate Wednesday that she missed the House hearings because she was at the United Nations General Assembly.

"Ako na po ang magsasakripisyo para maipasa na ang budget ng PCOO. Ako ay nagdesisyon na mag-resign na po," Uson said.

(I will make the sacrifice so that the PCOO budget can be passed. I have decided to resign.)

"Hindi po ito katapusan ng laban, umpisa lang po ito," said Uson, a longtime supporter of President Rodrigo Duterte who has 5 million followers on Facebook.

(This is not the end. This is just the beginning.)

Addressing her critics, Uson said: "'Wag kayo magkakamaling isipin na nagtagumpay kayo. Hindi ako nagbitiw sa posisyon dahil takot akong harapin kayo. Gusto ko lang na pag nagharap tayo ay patas ang laban."

(Do not make the mistake of thinking that you won. I did not resign because I am scared. I just want to have a fair chance when I face you.)

Duterte will likely accept Uson's resignation, said Special Assistant to the President Christopher "Bong" Go.

"Nirerespeto po naman ang kanyang pagre-resign at nagpapasalamat rin kami kay Asec. Mocha sa kanyang naging serbisyo po sa gobyernong Duterte. Naging good ally po siya," Go told GMA News TV.

(We respect her resignation and we thank Asec. Mocha for her service to the Duterte government. She was a good ally.)

• PCOO budget hearing deferred because of Mocha Uson's absence

Uson alleged that several left-leaning lawmakers were deliberately stalling the PCOO's budget after her interview with some Lumad, who claimed they were being "used" by the left against Duterte.

She also slammed congressmen for politicizing budget deliberations.

"Kayong ilang mga mambabatas ay gingamit ang posisyon upang takutin ang ilang ahensya ng gobyerno na hindi sumasakay sa inyong pansariling agenda," she said.

(Some lawmakers have been using their position to intimidate some government agencies who do not adhere to their personal agenda.)

Uson recently drew flak over a video about federalism that featured dancing and another clip that courted protests from the deaf community.
