Top officials at the campaign committee for House Republicans said Tuesday they weren't aware of anonymous Twitter accounts that were used ahead of the midterms to share internal polling data with outside groups, potentially violating campaign finance laws. "I don't know anything about it," Oregon GOP Rep. Greg Walden, the chairman of the National Republican Campaign Committee, told CNN Tuesday. CNN reported Monday that NRCC and at least two outside groups -- American Crossroads and American Action Network --  masked their identities through anonymous Twitter accounts to share information about House races. Campaign finance experts said that pushed the limits of election laws that bar coordination between campaigns and outside groups, such as super PACs and nonprofits.
