The president lashed out in a series of Sunday morning tweets, renewing his attack on the New York Times in an apparent continuation of his longstanding campaign to discredit news organisations which cover stories he does not approve of.
In the posts he suggests, without providing evidence, that the publication has shifted its focus from coverage of Special Counsel Robert Mueller's investigation into his campaign's links with Russia to "a Racism Witch Hunt".
Having repeated his unsubstantiated claims that "reporting is so false, biased and evil", Mr Trump said: "With all that this Administration has accomplished, think what my Poll Numbers would be if we had an honest Media, which we do not!"
A poll conducted for Fox News, an network consistently supportive of the president, showed this week that his disapproval rating had leapt while his approval rating had fallen.
That followed a separate poll which indicated he would lose heavily in 2020 to any of the four leading Democratic candidates.
