A watchdog group is filing a complaint against former Rhode Island congressional candidate Russell Taub, claiming he's running a scam political action committee.  Taub allegedly violated federal law by failing to register the Keeping America in Republican Control PAC with the Federal Election Commission or send any money to candidates, according to the Washington-based Foundation for Accountability and Civic Trust.  Taub, a Republican who lost to incumbent Democrat David Ciccilline in 2016, is alleged to have raised more than one-and-a-half-million dollars.
