"Through the years we served together in the City Council, I have witnessed, time and again, the dedication that Melinda Katz has shown advocating for Queens,” said Comrie in a statement.
“Melinda has a proven track record of advocating for better schools, the creation of affordable and senior housing, and better jobs,” said Comrie, adding that Katz has also been "dynamic in the fight against the closure of firehouses, hospitals, and senior centers.”
Katz, a former Councilwoman, was also backed by two other former rivals — Barry Grodenchik, the Deputy Queens borough president, and state Sen. Jose Peralta — both of whom ended their bids in May.
Katz has accumulated numerous high-profile endorsements, including the Queens County Democratic Party, the Working Families Party and the late Mayor Ed Koch.
Current Queens Borough President Helen Marshall cannot run for re-election due to term limits.
