President Barack Obama is facing mounting pressure to produce proof the Russians were behind the cyberattacks in the presidential election, The Hill reports.
Despite its assessment that the Russians tried to interfere during the campaign, the administration has produced little evidence so far to back up its claims.
And it has not released any evidence to confirm claims from anonymous officials that the CIA is convinced Russian President Vladimir Putin coordinated the hacking to ensure President-elect Donald Trump's victory, according to the Hill.
Trump aide Kellyanne Conway said "They should not be leaking to the media. If there's evidence, let's see it."
