President Trump on Saturday claimed China "may" have been behind the massive cyberattack on U.S. government systems. His claim came one day after Secretary of State Mike Pompeo said the attack was "pretty clearly" perpetrated by Russians

Russians were widely suspected of having carried out the attack, but no government official or entity had publicly confirmed who was behind it prior to Pompeo’s comments. Russian President Vladimir Putin has denied the country's involvement.
