National: Russian election meddling in 2018 may be difficult for Congress to stop | USA Today
With congressional elections just a year away, lawmakers are scrambling to stop Russia from hacking state election systems and using social media to create chaos and uncertainty among voters. But Congress may be stymied by its reluctance to regulate private tech companies and by states' traditional aversion to any federal control over their elections, analysts say. The burden on the three congressional committees conducting investigations into Russian meddling has become much greater than simply trying to prevent Kremlin-linked groups from stealing campaign emails, as they allegedly did last year in cyber attacks against the Democratic National Committee and Hillary Clinton's presidential campaign.
