US president Donald Trump was active on Twitter on Wednesday morning, using his ‘executive time’ to lash out at adversaries, this time taking aim at the US media and predicting the downfall of the free press, which he believes he keeps in business.

“The Press has never been more dishonest than it is today,” Mr Trump tweeted.

“In six years, they all go BUST!”

In a second tweet he singled out the American daily newspaper The Washington Post, possibly because the Post covers national politics and the workings of the federal government — and is owned by Amazon founder Jeff Bezos, who is a Trump nemesis.

Mr Trump then took aim at his other nemesis: The left-leaning New York Times in a tweet which appears to be in response to front page stories run by the Times alleging that an examination by the newspaper finds that Mr Trump’s “sustained, secretive assault on the machinery of federal law enforcement” has exposed him to allegations of “obstruction of justice.”

On Wednesday morning, senior adviser to the US President Kellyanne Conway defended Mr Trump against allegations that he has interfered with justice and is a “Russian asset”.

When CNN’s Chris Cuomo interviewed Ms Conway she stated: “The media loves imbuing credibility on to people who come bearing anti-Trump gifts and it’s absolute c**p and it has to stop.”

Mr Trump’s feud with the media is longstanding and ongoing, with the US president often referring to coverage that is critical of his administration as “fake news”.

His views have spread to his constituents with some of them attacking the media on Mr Trump’s behalf.

Earlier this month a BBC cameraman was attacked by a Donald Trump supporter after the US President whipped a crowd into a frenzy against the media.

Ron Skeans was filming Mr Trump’s rally in El Paso, Texas, when a man in a ‘Make America Great Again’ hat launched at him.

According to Gary O’Donoghue, the BBC’s Washington correspondent, the man climbed onto a platform used by reporters and pushed the camera into his colleague.

He then continued to push Mr Skeans, until security officers intervened.

Moments earlier, Mr Trump had been pointing at journalists and jeered “fake news”.

Mr Trump told the crowd that the media had “gone down a long way” and that it “refuses to acknowledge” his achievements.

Mr O’Donoghue told the Today program: “It was an incredibly violent attack. Fortunately our cameraman is fine, he is made of stern stuff.”

In an unprecedented move in November last year, Mr Trump revoked a CNN reporter’s media credentials despite America’s freedom of speech laws outlines in the First Amendment.
