Carl Bernstein warned early Saturday that President Trump's repeated criticisms of the media is "more treacherous" than President Richard Nixon's.

"The most dangerous 'enemy of the people' is presidential lying—always. Attacks on press by @realDonaldTrump more treacherous than Nixon's," Bernstein tweeted.

Real news (not fake) is that @realDonaldTrump trying to make conduct of press the issue instead of egregious (and unhinged)conduct of POTUS. — Carl Bernstein (@carlbernstein) February 18, 2017



He also noted that when the press reported on Hillary Clinton's unauthorized email server, Trump saw journalists as "patriots."

Trump has ratcheted up his rhetoric against the "fake" news media, using part of a press conference Thursday to remark on the "hatred" from journalists.

The president has also taken to Twitter to accuse reporters of making up stories and "'sources'" after leaks about Mike Flynn misleading administration officials on his communications with Russia led to his resignation Monday.

FAKE NEWS media, which makes up stories and "sources," is far more effective than the discredited Democrats - but they are fading fast! — Donald J. Trump (@realDonaldTrump) February 16, 2017



Bernstein is best known for his investigative reporting for the Washington Post that shed light on the Watergate scandal, leading to Nixon's resignation in 1974.

In December, Bernstein warned against Trump's "disdain for the truth."

"Trump lives and thrives in a fact-free environment," Bernstein said on CNN. "No president, including Richard Nixon, has been so ignorant of fact and disdains fact in the way this president-elect does."
