The White House says U.S. President Barack Obama has ordered an investigation into cyberattacks during the recent presidential election that Washington blamed on Russia.
Obama has ordered U.S. intelligence agencies to deliver a report before he leaves office on January 20, the White House said.
Obama's successor, President-elect Donald Trump, has cast doubt on Russia's role in the cyberattacks and praised Russian President Vladimir Putin during the campaign.
The hacks targeted the U.S. Democratic National Committee and a key aide to presidential candidate Hillary Clinton.
The U.S. government has publicly accused the Russian government of involvement in the hack of Democratic Party officials.
Obama's homeland security adviser, Lisa Monaco, told reporters on December 9 that the report's results would be shared with lawmakers and the public.
