Two businessmen tied to the nonprofit, which Mayor de Blasio recently closed after it was accused of using nonprofit funds to further the mayor's political agenda, are under federal investigation.

"A federal corruption investigation examining New York City police officials, a correction union leader and businessmen with fundraising ties to Mayor Bill de Blasio has expanded into a probe of the mayor’s campaign fundraising, people familiar with the matter said.

"The U.S. attorney’s office in Manhattan is scrutinizing the activities of two businessmen who are a focus of a federal probe into the New York Police Department and who served on the mayor’s inaugural committee, the people said. One of the businessmen held a fundraiser at his home for the Campaign for One New York, a nonprofit supporting the mayor’s agenda and run by his allies, and another bundled more than $40,000 in contributions to Mr. de Blasio’s 2013 campaign, records show."--Rebecca Davis O'Brien and Josh Dawsey, The Washington Post
