Geraldo Rivera said criticism of President Trump's summit with Russian leader Vladimir Putin has been "absolutely overblown" because there's such widespread anti-Trump sentiment in the mainstream media.

Following the two leaders' press conference in Helsinki, Finland, on Monday, some pundits and Democratic lawmakers suggested that Trump was "treasonous" or a "traitor" for appearing to side with Putin, rather than with the U.S. intelligence community, on Russian meddling in the 2016 elections.

Trump clarified his remarks at the White House on Tuesday, saying that he misspoke and accepts the intelligence community's conclusions.

On "Fox & Friends," Rivera said the coverage of the Helsinki summit "bordered on hysterical."

"There is such deep hatred of this president. There is such disquiet. There is such a divide in this country. There is such unbridled passion that even people who can normally have a reasonable discussion, just go overboard," Rivera said.

"I think that Trump derangement syndrome is a real thing."
