Washington (CNN) Former Director of National Intelligence James Clapper confirmed Thursday that Donald Trump was briefed on US intelligence findings that Russian President Vladimir Putin personally ordered cyberattacks to attempt to sway the 2016 presidential election.

Clapper told CNN's "New Day" that he and other intelligence officers briefed Trump, who was President-elect at the time, and his team on January 6, 2017. CNN has previously reported that Trump was briefed on the report by the US intelligence community, which found that Putin ordered an "influence campaign" aimed at helping Trump and hurting Hillary Clinton in the 2016 presidential election.

In the "New Day" interview Thursday, Clapper said Trump listened to the briefing with "some skepticism."

"What struck me and others as quite unusual was before we left the room, they started writing a press release about our encounter and were trying to say that the Russian meddling -- the Russian interference had no impact on the election," Clapper said Thursday. "We didn't say that. We could not say that, that isn't the charter or capability of the intelligence community to do that. But I do think there was skepticism from the get-go -- from that day to this day -- that indicated that anything that attacked the legitimacy or questioned the legitimacy of now-President Trump's election, he just couldn't get his head around. He exhibited that that day and he has ever since."

Clapper has frequently criticized Trump's behavior toward Russia, including in his news conference Monday with Putin in Helsinki, Finland.
