Tenure in the New York State Assembly
In December 2019, Rivera transitioned to elective politics by declaring his candidacy for the 149th District of the New York State Assembly. He first secured the Democratic nomination by defeating attorney Adam Bojak and former Niagara District Common Councilman Robert Quintana in the primary. He subsequently won the general election in November, defeating Republican nominee Joseph Totaro.
Rivera maintained his seat through subsequent election cycles. In 2022, he defeated Republican candidate and former school board member Ralph R. Hernandez. By 2024, his position was further solidified when he was re-elected without an opponent.
During his time in the Assembly, Rivera took on significant leadership roles. He chaired the Commission on Administrative Regulations Review (a body tasked with overseeing agency rules) and the Subcommittee on Regional Tourism Development, while contributing as a member to ten additional committees.
Transition to the New York State Senate
In 2026, Rivera sought a higher office by running for New York's 61st State Senate district. He challenged the incumbent Democrat, Jeremy Zellner, who had won a special election on February 3, 2026, to replace Sean Ryan after Ryan was elected mayor of Buffalo.
The contest concluded on June 23, 2026, with Rivera defeating Senator Zellner. The final tally saw Rivera receive 10,076 votes compared to Zellner's 8,270, representing a 55-45 victory. Following this win, Rivera faced no Republican opposition in the general election.
