Currently, Stone serves as chair of the assembly’s judiciary committee, reviewing legislation for a variety of issues including family law, tort liability and immunity, and civil practice. He’s also written laws to protect the civil rights of LGBT+ community members, sexually exploited youths, and immigrants.

Stone won his fifth term in the November 2020 election.
