Senate Majority Leader-designate Andrea Stewart-Cousins next month will headline a fundraiser for Suffolk County Executive Steve Bellone.

The fundraiser, Bellone’s 8th Annual Cocktail Reception, will also serve as a formal kickoff event for his 2019 re-election bid. The event will take place at Coindre Hall in Huntington.

“Smart, shrewd, and suburban — Senate Majority Leader-elect Stewart-Cousins is the voice Long Islanders need in Albany to protect their schools and pocketbooks,” Bellone said. “I am honored that she has agreed to headline this event as we gear up for the year ahead.”

Stewart-Cousins on Monday was re-elected the leader of the Democratic conference in the state Senate and is poised to become the first woman to serve as the top official in a majority conference in New York state government.

Democrats in the state Senate this month secured a landslide majority and could have as many as 40 seats in the 63-member Senate chamber in 2019.
