A group founded by Hillary Clinton ally David Brock filed three complaints with the Federal Election Commission Tuesday against the Bernie Sanders’ campaign and two allied outside groups. One complaint from the American Democracy Legal Fund alleges Sanders’ campaign accepted more money from individual donors than allowed under federal law. Another accuses the campaign of failing to include proper disclosure on a Facebook ad it ran after the New Hampshire primary. The third claims a pro-Sanders super PAC has improperly using Sanders’ name, and also alleges illegal coordination.
