According to international media, which country hacked American President's election in 2016?

Former President Barack Obama ordered US intelligence agencies to assess whether Russia tried to intervene in the election after a cyber attack on the Democratic National Committee in July 2016 and the publication of thousands of hacked personal emails from Hillary Clinton's campaign manager in the month before the 8 November election. Obama told intelligence officials to deliver a report on possible foreign interference before he left the White House in January 2017. The Central Intelligence Agency, the Federal Bureau of Investigation and the National Security Agency concluded in a report declassified in January that Russian President Vladimir Putin ordered a campaign not just to undermine confidence in the US electoral system but to affect the outcome.
