Senator (2019–present) Committee Chairmanships • Committee on Public Order and Dangerous Drugs • Committee on National Defense and Security; Peace, Reconciliation and Unification • Committee on Civil Service, Government Reorganization and Professional Regulation
18th Congress Dela Rosa placed a bid for a Senate seat and won placing fifth overall, garnering 19 million votes in the
2019 Philippine Senate election. Dela Rosa took office on June 30, 2019. Dela Rosa Chaired the Senate Committee on Public Order and Dangerous Drugs. In August 2019, Dela Rosa caused controversy when he said in an interview that convicted rapist-murderer and former
Calauan mayor
Antonio Sanchez "deserves a second chance"; Dela Rosa said that "if it is determined by the Board of Pardons and Parole that he deserves that commutation, then why not? He deserves a second chance in life." Dela Rosa was highlighted in the news when he got angry at
a student leader who raised the issue of what Dela Rosa said regarding Sanchez' possible release while at a Senate hearing on bringing back the mandatory
Reserve Officers' Training Corps (ROTC) for senior high school students; Dela Rosa said that the student's criticism was "irrelevant to the topic that was being discussed" during the session. Despite some issues that were raised against him, Dela Rosa filed bills including bringing back capital punishment to the country—specifically for drug traffickers—which was not passed. Among the initial bills he prioritized were an act regulating the use of government ambulances, the
Department of Overseas Filipino Act, police scholarships for qualifying students in all barangays, establishing crisis centers for street children in every region in the Philippines, the creation of barangay community peace and order councils, and job training for older workers. In June 2021, Dela Rosa sponsored the
Bureau of Fire Protection (BFP) Modernization Bill in the plenary for the Senate to be ratified. The amendment, which Dela Rosa inserted without authorization, would allow BFP personnel to carry short firearms during fire emergencies and disasters, provided that training will be undertaken with the Department of Interior and Local Government and the Philippine National Police. Dela Rosa said only 2,282 out the total 30,290 BFP personnel would be allowed to carry short firearms to protect their colleagues. He explained in Filipino,
"...the usual complaint of our firefighters, that during fire incidents, there are people who try to take away their water hoses. Sometimes, there are firefighters who get stabbed because there are people who want their houses to be saved from the fire first." Some senators declined to ratify the reform but were outvoted; President Rodrigo Duterte signed the bill into law in September 2021. Dela Rosa voted in favor of a law signed in September 2021 by President Duterte that imposed additional taxes on
Philippine Offshore Gaming Operators (POGOs).
2022 presidential campaign On October 8, 2021, the
PDP–Laban faction supported by President Duterte announced dela Rosa as their candidate for
president of the Philippines in the
2022 election, the same day dela Rosa filed his certificate of candidacy before the
Commission on Elections. However, on November 13, 2021, the same day that Sara Duterte filed her candidacy as the running mate of
Bongbong Marcos, dela Rosa withdrew his candidacy as per party's decision.

Philippine National Police in its
operation against Quiboloy. By 2022, dela Rosa's entire senate staff is composed of members of his family. His daughter Marianne Kristel "Macky" dela Rosa-Estoesta is his chief of staff, his niece Joanna Cedie dela Rosa is his media relations officer, and Jessica May "Mingkay" dela Rosa is his appointments secretary. Upon the opening of the
19th Congress in July 2022, Dela Rosa filed his priority bills, which included the institutionalization of the
government's anti-communist insurgency task force; the reimposition of the death penalty for convicted large-scale drug traffickers; and the amendment of the Party-list System Act to disallow
party-lists linked with terrorist organizations from joining Congress. In an effort to decongest prisons, Dela Rosa filed a bill decriminalizing illegal drug use—excluding illegal drug pushing, manufacturing, and trafficking—and automatically sending drug users to rehabilitation centers. He was discouraged by strong opposition from law enforcement agencies over his proposal. In September 2023, Dela Rosa along with Senator
Risa Hontiveros led a senate probe against the
Socorro Bayanihan Services for allegations of being a cult and abuse. After illegal activities of POGOs were exposed in 2022, Dela Rosa suggested a ban may be a possible solution; a year later, he recommended the creation of a dedicated zone for POGOs, where the gambling corporations are restricted to operate. In 2024, a
House quadruple committee investigation into the possible links of POGOs to the
illegal drug trade and other crimes prompted Dela Rosa to remark that questioning the illegal activities of POGOS was "unnecessary"; Dela Rosa alleged that the House was plotting to implicate him and President Duterte in the extrajudicial killings that occurred during the
war on drugs. During the House hearings, Kerwin Espinosa testified that dela Rosa coerced him to link Senator
Leila de Lima to the drug trade. In regards to the
International Criminal Court's (ICC)
investigation in the Philippines, Dela Rosa has maintained that since the Philippines withdrew from the in 2019, the ICC no longer has jurisdiction over allegations related to the drug war killings during Duterte's presidency. This was contrary to fact checks by media outlets stating that the ICC has jurisdiction over crimes committed during the Philippines' membership. In January 2023, Dela Rosa said he is ready for a probe by the ICC and would cooperate if the Marcos administration decides so but was confident the government will not. By 2024, Dela Rosa has been repeatedly skeptical on President Marcos' pronouncements that the country will not cooperate with the ICC.
2025 senatorial campaign On October 3, 2024, Dela Rosa filed his candidacy for the
2025 Philippine Senate elections under the
Duterte-led Partido Demokratiko Pilipino (PDP). Following the
arrest of Rodrigo Duterte by the
International Criminal Court (ICC) in March 2025, he stated that he is willing to join Duterte in
The Hague if all legal remedies are exhausted. However, dela Rosa went to an undisclosed location within the Philippines. He was considered to be hiding from the authorities. He was re-elected as senator in May 2025, placing 3rd in the official results, with 20,773,946 of votes.
Impeachment of Sara Duterte Dela Rosa has supported Vice President
Sara Duterte in regards to the
impeachment proceedings against her. In May 2025, Dela Rosa projected that there are enough senators in the upcoming 20th Congress to acquit Duterte. He filed a motion to have the proceedings dismissed before the Senators took oath as judges in an impeachment trial court on June 10, 2025. The impeachment complaint was remanded back to the House of Representatives instead after
Alan Peter Cayetano amended the motion. This move was tagged as a victory by Dela Rosa and is "effectively a dismissal". On June 14, Dela Rosa posted a
deepfake AI-generated video showing two students testifying that the impeachment process was selective and politically motivated. When informed it was an AI video, Dela Rosa maintained that the video creator had a point.
Alleged ICC warrant and disappearance After interior secretary Jonvic Remulla claimed that he has received an "unofficial" warrant of arrest for Ronald dela Rosa from the
International Criminal Court, Dela Rosa was noted to be absent from the Senate since November 10, 2025 and has not reported for duty since then. On February 13, 2026, the ICC included dela Rosa among eight indirect co-perpetrators in the crimes against humanity case against president Duterte during the Philippine drug war. ==Personal life==
