'Schmuck': Trump taunted over old tweet after claiming he never watches 'dumb' CNN anchor Don Lemon

US President Donald Trump has lashed out at the media in the wake of several reporting errors last week including a New York Times story that details some of his daily habits. The profile, which ran over the weekend, claimed that Trump watches between four and eight hours of TV and consumes a dozen Diet Cokes a day.

Citing people close to Trump, the Times reported that the president usually begins his day around 5:30AM by turning on CNN before flipping over to Fox News' "Fox & Friends." Sometimes he watches MSNBC's "Morning Joe" because it apparently works him up.

He also occasionally "hate-watches" CNN host Don Lemon, a vocal critic of Trump, NYT reported.

However, Trump furiously disputed the report on Monday as "another false story".

"Another false story, this time in the Failing @nytimes, that I watch 4-8 hours of television a day - Wrong! Also, I seldom, if ever, watch CNN or MSNBC, both of which I consider Fake News. I never watch Don Lemon, who I once called the 'dumbest man on television!' Bad Reporting," Trump tweeted.

NYT deputy managing editor Clifford Levy defended the newspaper's reporting saying: "We stand by our reporting, sourced from interviews with 60 advisers, associates, friends and members of Congress."

Trump has frequently slammed stories that are critical of him and often refers to mainstream news outlets as the "fake news media".

CNN hit back at Trump's attack on Lemon, saying it's "sad" to see the president engage in bullying behaviour. A spokesperson said in a statement: "In a world where bullies torment kids on social media to devastating effect on a regular basis with insults and name calling, it is sad to see our president engaging in the very same behavior himself."

However, it didn't take too long for Twitter users to find an old Trump tweet from December 2015 in which he praised Don Lemon just six months into his presidential campaign.

Twitter immediately proceeded to mock the president for saying he never watched Don Lemon, noting "there's always a tweet for everything".

"Jeez...there really is an old @realdonaldtrump tweet to refute everything that comes out of his face," one person tweeted.

British tennis star Andy Murray also mocked Trump over his attack on Don Lemon saying: "How do you know he's so dumb if you never watch him? #impressive".

"Donald Trump's definition of fake news is 'news that is true, but doesn't make me look great'," one person added.
