FBI director James Comey told a Senate Intelligence Committee Tuesday that Russia also successfully hacked Republicans during the election.
"There were successful penetrations of some groups and campaigns, particularly at the state level on the Republican side of the aisle, and some limited penetration of old [Republican National Committee] domains,’’ Comey said.
Comey later added that there are no signs that the Trump campaign or the current Republican National Committee were hacked, according to CNN.
Top intelligence officials added that the Russians disclosed less material from the hacking of Republicans than they did with the Democrats' emails, The Wall Street Journal reports.
Director of National Intelligence James Clapper told the committee that intelligence officials can now say with "high confidence" that Russia hacked presidential candidate Hillary Clinton to make her look bad in comparison to her Republican opponent, Donald Trump.
"We have multiple high-quality sources that contribute to that assessment," Clapper said. "Attributing cyber operations is difficult but not impossible."
Clapper didn't go into detail about how the information was collected.
He only added that their report is based on technical data, open-source information, and human sources, CNN reports.
Before this briefing, Trump had rejected the findings of the intelligence community, calling them politically partisan.
After this briefing, however, Trump changed his tune, issuing a statement that said Russia, like China, is "consistently trying to break through the cyberinfrastructure of our government institutions."
