WLNI-gun-lawsRICHMOND, Va. (AP) _ One of Democratic Gov. Terry McAuliffe’s biggest donors and political allies has turned against him with an advertisement campaign condemning a deal he struck with GOP leaders on gun policy. Former New York Mayor Michael Bloomberg’s group Everytown for Gun Safety took out a full-page advertisement in a Richmond newspaper on Tuesday declaring that “Terry McAuliffe is wrong” and urging residents to pressure him into scrapping the deal. Everytown has also been running online ads comparing McAuliffe to the head of the National Rifle Association. McAuliffe’s administration is standing by the deal, which it says as a whole will make residents safer. Bloomberg has been one of McAuliffe’s biggest political patrons. His political action committee was McAuliffe’s single largest non-party donor during his successful 2013 gubernatorial bid.
