The Democrat trying to unseat longtime Brooklyn state Sen. Marty Golden said Thursday that one of the “anti-corruption” reforms required in Albany is barring lawmakers from spending campaign funds at a family business.

Golden has showered Bay Ridge Manor, a family-owned catering hall, with $776,643 from his campaign since at least 2001, records show.

“It’s ludicrous that Marty Golden has spent nearly $800,000 of his campaign funds at his family’s catering hall,” charged Andrew Gounardes. “He also used campaign funds to pay for his country club dues and car payments. No legislator should be able to get rich off of morally bankrupt behavior.”

Although Golden once owned the catering hall, he sold it to his brother after being elected in 2002.

Gounardes, who is counsel for Brooklyn Borough President Eric Adams, calls his reform proposal the “Golden Rule.”

Reps for Golden did not immediately return messages.
