CITY HALL — He's going all the way.
City Comptroller John Liu will formally launch his bid for mayor this weekend, a spokesman for his campaign said.
The former city councilman, whose campaign has been under federal investigation, is planning to make his announcement this Sunday, despite his legal troubles, consultant Bill Lynch said.
City Council Speaker Christine Quinn made her bid official last weekend, making Liu the only major candidate in the race left to formally declare his intentions — even though he's been appearing frequently at candidate forums.
The news, which was first reported by Politicker, came shortly after Liu announced plans to host three town hall meetings across the city on the NYPD’s controversial stop-and-frisk policy and other public safety issues "so that New Yorkers can voice their concerns on civil rights and security issues," he said.
Liu has campaigned on his record of saving the city cash as comptroller, and he has called for an end to stop-and-frisk, as well as an end to school closures and co-locations.
