Asm. Rebecca Kassay — The Commons Gallery

Rebecca Kassay represents AD-4, a D+6 district on Long Island that has become one of the most competitive seats in the chamber; she won her 2024 general election over Edward A.

The district is majority-homeowner (78.7%) with a median household income of $126,580 and a registration breakdown of 35.0% Democrat, 28.7% Republican, and 31.7% Independent, reflecting a suburban electorate with a substantial unaffiliated voter bloc.

A10329 2026-03-24

An act to amend the Racing, Pari-Mutuel Wagering and Breeding Law, in relation to requiring mobile sports wagering operators to share monthly invoice statements to authorized consumers

Assemblywoman Kassay presented A10329, which would require mobile sports betting operators to send monthly invoices to users detailing their wagering activity, winnings, losses, and problem gambling resources. The bill addresses a growing crisis in New York's mobile sports betting market: in 2025, bettors wagered over $26 billion, problem gambling hotline calls spiked 26 percent, and researchers estimate 22 percent of bettors show signs of problem gambling. Kassay, who identified the issue while working with constituents, said the monthly statements would provide transparency about betting habits and connect struggling bettors with help. The measure is part of a broader legislative package on problem gambling being advanced by the Assembly.

Mobile Sports Betting Monthly Invoice Bill

The Assembly passed a bill sponsored by Assemblymember Kassay requiring mobile sports betting apps to send monthly invoices to users detailing wagering amounts, winnings, losses, and betting habits, along with problem gambling hotline information. The bill takes effect January 1st following the Governor's signature. Kassay cited alarming statistics: $26 billion wagered in New York in 2025, a 26 percent spike in problem gambling hotline calls, and research suggesting 22 percent of bettors exhibit signs of problem gambling. She noted that minors are accessing betting apps through VPNs and becoming addicted at young ages. Supporters including Ms. Woerner cited expert testimony that providing wagering information helps change behavior. However, Assemblymember Morinello, drawing on his experience representing bookmakers, argued the invoices are ineffective because users already have access to betting information and the real problem is the addictive nature of mobile betting itself. He criticized the state's legalization of mobile betting as a "money grab" without consideration for families and youth. Fitzpatrick similarly opposed the bill, arguing the best solution is to prohibit mobile gambling for ages 18-25 and criticizing the state for promoting VLTs, marijuana, and mobile sports betting to young people. Despite the opposition, the bill passed.

An act to amend the Public Authorities Law, in relation to the Septic System Replacement Fund

The Assembly passed legislation expanding the Septic System Replacement Fund to facilitate reimbursement for septic and cesspool upgrades across New York State. Sponsored by Assemblywoman Kassay, the bill addresses widespread contamination from antiquated systems, particularly on Long Island where 70 percent of Suffolk County residents rely on conventional cesspools and septic systems that fail to filter nitrogen and other pollutants. Multiple members testified that the upgrades are critical for protecting groundwater and preventing harmful algal blooms in bays, harbors, and beaches. Assemblywoman Giglio noted replacement costs can reach $35,000 to $50,000 per property. Assemblyman Schiavoni emphasized that Long Island has no viable alternative drinking water source other than the aquifer beneath it, making the measure essential for coastal communities.

An act to amend the General Municipal Law, in relation to removing certain requirements for official websites of small municipalities; chapter amendment to Laws of 2024 relating to requiring municipalities to maintain municipal websites

Assemblywoman Kassay introduced a chapter amendment to last year's municipal website legislation, addressing concerns about the impact on smaller municipalities. The amendment establishes a 1,500-resident population threshold, exempting municipalities below that size from the requirement to maintain .gov websites but encouraging compliance to the extent practicable. Municipalities above the threshold can create website pages on existing town or county websites rather than building separate infrastructure. The implementation timeline was extended from 180 days to one year. The 1,500-resident threshold was negotiated with the Governor, Legislature, and municipal associations including NYCOM. Of approximately 1,500 municipalities in New York State, 300 fall below the threshold, and 80 percent of those already have websites. Kassay emphasized that .gov domains, restricted to government entities, provide enhanced cybersecurity and prevent fraudulent websites from impersonating municipal sites.
