FBI Probing New York Mayor Bill de Blasio’s Campaign, Foundation Fundraising Activities

U.S. Attorney Preet Bharara now has New York Mayor Bill de Blasio in his crosshairs—investigating de Blasio's campaign fundraising activities as part of a widening probe into New York Police Department corruption, sources said last week.

The feds are looking at how the mayor solicits campaign cash from members of the real-estate industry—and the fundraising activities of his former campaign treasurer, Ross Offinger, the sources said.

A source who dealt with Offinger said he "plays fast and loose" with campaign-finance regulations.
