Donald Trump's fiery feud with the American media has taken a bizarre twist after the US President tweeted out a modified video of one of his World Wrestling Entertainment (WWE) appearances to his 33 million followers on Sunday 2 July.

The 28-second-long clip shows the property tycoon clotheslining WWE boss Vince McMahon, whose wife, Linda, serves as the administrator of the Small Business Administration under Trump, during their "Battle of the Billionaires" match at Wrestlemania 23 in Detroit, Michigan, in 2007.

But instead of McMahon's shocked face, the modified video had the famous red and white CNN logo in its place. The posting came just days after three CNN staffers – a reporter and two editors – resigned from the broadcaster following the retraction of a story.

The spiked piece, which cited just one anonymous source, related to a member of Trump's transition team and an alleged investigation into a Russian investment fund.

"On June 22, 2017, published a story connecting Anthony Scaramucci with investigations into the Russian Direct Investment Fund," CNN said. "That story did not meet CNN's editorial standards and has been retracted. Links to the story have been disabled. CNN apologises to Mr Scaramucci."

Trump, who turned 71 in June, has become known for a his "fake news" slogan. He recently lashed out at the hosts of MSNBC's Morning Joe show, Joe Scarborough and Mika Brzezinski. Trump accused Brzezinski, a mother-of-two, of having "low IQ" as well as being "crazy" and "bleeding badly from a face-lift."

Scarborough and Brzezinski hit back in the Washington Post and on their show accusing unnamed White House officials of attempting to "blackmail" them.

"This year, top White House staff members warned that the National Enquirer was planning to publish a negative article about us unless we begged the president to have the story spiked. We ignored their desperate pleas," the duo wrote.

Scarborough added: "The calls kept coming, and kept coming. And they were like 'Call, you need to call. Please call. Come on, Joe. Just pick up the phone and call him'. It's blackmail."

Trump took to Twitter again to brand the claims as "fake news". His administration has also sought to reform how American outlets cover White House press briefings, with broadcasters recently being asked to turn off their cameras and not film the event. The controversial move follows months of ridicule of Press Secretary Sean Spicer on NBC's comedy show Saturday Night Live.
