Buffalo Mayor Byron Brown has been replaced as the state Democratic Party's chairman.
Governor Andrew Cuomo announced early Monday he has selected Jay Jacobs to take over.
Jacobs is the Nassau County Democratic Chairman.
In a statement, Cuomo calls Jacobs "an outstanding champion for Long Island ... with an unparalleled record of bringing Democrats together to win historic victories."
Brown was appointed chairman in 2016.
Cuomo thanked Brown for securing key districts for Democrats last year.
