The candidate's top five accomplishments and contributions for the last 15 years or so

Belgica was the youth adviser of the Manila Mayor’s Office on Youth Affairs from 2000-2004 and was elected as a councilor in the 6th District of the City of Manila in 2004. From 2011 to 2012, he was a board member of the Anti-Drug Abuse Council of Manila.

In 2017, Duterte issued Executive Order No. 43 creating the PACC to directly assist the president in investigating administrative cases primarily involving graft or corruption against all presidential appointees. It is also mandated to recommend the filing of a complaint before the Office of the Ombudsman and Department of Justice “when appropriate.” The PACC was formed following the ombudsman's fact-finding investigation while a DOJ Task Force Against Corruption was formed after corruption allegations at the Philippine Health Insurance Corp.

Belgica was appointed PACC commissioner in January 2018. In his weekly public address in late December 2020, Duterte read off the names of current and former officials determined by the PACC as receiving kickbacks from public work projects, although the chief executive admitted that the report was not based on “hard evidence.” Included on the list was Occidental Mindoro Rep. Josephine Ramirez-Sato, who claimed that the accusation was politically motivated, saying Belgica was a party-mate of her political rival planning to run in the 2022 elections. Other officials named in the report denied the allegations and urged the president and PACC to release the names of the complainants.

After the death of then-Chairman Dante Jimenez, Belgica was appointed chairman of the PACC in March 2021. He spearheaded a Task Force on Lifestyle Check to probe unexplained wealth of officials in the executive branch but transmitted reports only to the Office of the President for Duterte’s consideration. Throughout Belgica’s term, the PACC received and acted on at least 9,000 complaints of corruption in government.

Towards the end of his term, Belgica oversaw the creation of the 49-member National Anti-Corruption Coordinating Council which aims to coordinate anti-corruption efforts by installing bodies down to the barangays to facilitate those efforts on the local level as well as serving “preventive and educative functions” in all its levels. The launch of the NACC’s umbrella campaign dubbed “Project Kasangga: Aksyon Laban sa Korapsyon'' came hours after Duterte stated that he wanted the Senate Blue Ribbon Committee to stop its probe into the health department’s pandemic spending.

The NACC’s creation came after the Duterte administration already formed a “mega task force” against corruption in October 2020 that was tasked to probe “the entire government” for possible corruption. It was composed of the National Bureau of Investigation, the National Prosecution Service, the Office of the Special Assistant of the President, and the Anti-Money Laundering Council.

Greco’s brother, Anti-Red Tape Authority Secretary Jeremiah Belgica, was appointed as a member of the NACC.

In response to criticism of the new anti-graft body, Belgica admitted that there are overlaps in the new council’s functions with those of the Commission on Audit and the DOJ’s Task Force Against Corruption, but he noted that the PACC’s mandate is limited to presidential appointees to top government positions and insisted that there should be anti-corruption committees in all government offices.

After several positioning changes across at least two parties, Duterte and Sen. Christopher “Bong” Go, a longtime aide to the president, filed their certificates of candidacy for senator and president, respectively, under the relatively unknown PDDS, but later withdrew. PDDS now has two senatorial candidates for 2022 in Belgica and Lady Anne Sahidulla, though it maintains its alliance with the administration PDP-Laban faction led by Energy Secretary Alfonsi Cusi.
