Anti-gun Mayor Michael Bloomberg spends millions of his personal fortune fighting for gun control through his group Mayors Against Illegal Guns. But there’s one problem. According to Politico, the group’s website “is registered to, and handled by, official city government servers and staffers.”

Domain names for MAIG were registered in 2006 by the New York City Department of Information and Technology, and have remained on official city web servers ever since.

Yet the group’s “action fund,” through which he has piped at least $14 million of his own money in ads over gun control this year alone, is registered as a 501c4, a nonprofit “social welfare” group with the same tax status as, say, the Karl Rove-linked Crossroads GPS or Organizing for Action, President Obama’s grassroots arm. And it raises questions about why a website associated with the group is being managed by City Hall.
