In an exit interview with NBC News' Andrea Mitchell, Vice President Joe Biden said President-elect Donald Trump should do more to address criticism of his potential business conflicts of interest. 'He may sink in the swamp,' Biden added, referencing Trump's campaign pledge to 'drain the swamp' in Washington. Biden also addressed the controversy around the explosive unverified dossier linking Trump to Russia. Biden said the intelligence community felt an 'obligation to inform not only us but the president-elect that this was out there.'
