Democratic presidential candidate Bernie Sanders says he, opponent Hillary Clinton and the Democratic National Committee are working out their differences of opinion because they “want to defeat right-wing extremism in this country.”

Andrea Mitchell, guest host of NBC’s “Meet the Press,” asked Sanders on Sunday, “Is the DNC giving you a fair shot?”

Sanders: Look, we have had our differences of opinion with the DNC. But at the end of the day, the DNC, Hillary Clinton, and myself — we want to defeat right-wing extremism in this country. So we’re trying to work out our differences of opinion.

Earlier in December the Sanders campaign was barred from accessing the DNC’s national voter data file after several Sanders staffers improperly accessed voter information that was accidentally released by third-party vendor NGP VAN. One staffer was fired while two others were suspended. (RELATED: Sanders Staffer Fired After Improperly Accessing Clinton Voter Data [VIDEO])

The Sanders campaign also sued the DNC for not giving proper notice to their campaign before the suspension. (RELATED: Sanders Campaign Sues DNC For Shutting Off Access To Voter File)

The campaign has been highly critical of the DNC, claiming they favor front-runner Hillary Clinton. Sanders’ campaign manager Jeff Weaver said earlier this month that the DNC is “actively attempting to undermine our campaign.” (RELATED: Sanders Campaign Manager: DNC ‘Actively Attempting To Undermine Our Campaign’ [VIDEO])
