New York City Mayor Michael Bloomberg says his successor shouldn't live in the mansion that has long been the official mayoral residence.

The billionaire mayor said Tuesday using Gracie Mansion as a residence would reduce the number of official events that can be held there and would burden the city with unnecessary rental costs.

The mayor's comments come after the Wall Street Journal quoted political hopefuls including Bill Thompson and John Liu as saying they plan to move to Gracie Mansion if given the chance.

Liu said the mayor's comments were "like asking the president to move out of the White House," but he'd be willing to stay in his Queens home if there's a better public use for the mansion.

Bloomberg lives in an Upper East Side townhouse.
