Page "Gracie Mansion" Paragraph 11

Likewise, current mayor Michael Bloomberg, who is divorced and has had girlfriends during his time in office, has never resided at Gracie Mansion, although he uses it for meetings and events and has used the Mansion as a place for official visitors to stay while in the city.

At the beginning of Bloomberg's term he initiated a major restoration of the mansion, funded by an anonymous donor, suspected of being the billionaire mayor himself.
