While serving as United States Attorney, Neronha served two terms on the Attorney General's Advisory Committee, a group of sixteen United States Attorneys from across the country that advised the Attorney General of the United States on policy and operational matters affecting the Department of Justice nationwide. He also Co-Chaired the Operations, Management and Budget Subcommittee, responsible for reviewing and making recommendations concerning the approximately 2 billion-dollar budget for the entire United States Attorney component of the Department of Justice. During his seven years as United States Attorney, Neronha made public corruption the top priority of the United States Attorney's Office. Under his direction or continuation of previously started investigations, the Office prosecuted numerous cases against state and local elected officials, including a town mayor, three town councilmen, a state senator, a state representative, a House of Representatives Finance Chairman and a House Speaker, all of whom were sentenced to terms in federal prison. As United States Attorney, Neronha prioritized combating the state's opioid crisis, combining prosecution of major, cartel-linked drug trafficking organizations with prevention initiatives. He spoke personally to over 10,000 students at high schools and moderated panels at town halls across the state. He also advocated for a "smart" approach to reducing violent crime by focusing law enforcement resources on those individuals driving violent crime, while working in the community on crime prevention and to help secure employment for people leaving prison. He also prioritized the work of the Office's Civil Division, bringing cases to protect consumers, safeguard public money from waste and abuse, and protect the environment. Additionally, as United States Attorney, Neronha investigated Google regarding its business practice of assisting off-shore pharmacies unlawfully importing controlled substances, including opioids, into the United States. The investigation was initiated by Neronha’s predecessor, Robert Corrente. As a result of that investigation, Google forfeited 500 million dollars, one of the five largest forfeitures in U.S. history, of which 230 million dollars were returned to Rhode Island. Neronha was one of the U.S. attorneys who was asked to resign by Attorney General Jeff Sessions in the 2017 dismissal of U.S. attorneys.
Attorney General of Rhode Island
In October 2017, Neronha announced that he would seek the Democratic nomination for the office of Attorney General of Rhode Island. The previous Attorney General, Peter Kilmartin was termed limited. Neronha was the only Democrat running for the office. He ran against Compassion Party candidate Alan Gordon. In the general election, Neronha went defeated Alan Gordon of the Compassion Party 79.8% to 19.1%. As Attorney General of Rhode Island, Neronha joined a multi-state lawsuit to challenge the President's National Emergency Concerning the Southern Border of the United States. He has started a review into the Catholic Diocese of Providence to review sexual abuse claims against the church. The review is going through almost 70 years worth of records from the Diocese of Providence and will be modeled on the report from the Grand jury investigation of Catholic Church sexual abuse in Pennsylvania. Neronha, alongside GovernorGina Raimondo, has submitted a package of gun control bills for consideration by the General Assembly. These include making it illegal to purchase a gun on behalf of someone else who is prohibited from owning a gun themselves and requiring that all firearms be safely stored unless being used by the owner. He also supported some other bills such as an assault weapons ban bill and universal background check bill that were being considered by the assembly.
