Former City Comptroller and mayoral candidate John Liu has officially announced his candidacy for State Senate.
He will run against Queens City Councilman Tony Avella for the Democratic nomination for the 11th State Senate district in Queens.
Besides his role as Comptroller, Liu also served in the City Council representing Northeast Queens.
He recently sued the City's Campaign Finance Board for denying him matching funds during his 2013 mayoral run.
An official campaign kickoff is expected this week.
