President Donald Trump resumed his spat with Fox News on Monday night, accusing anchor Brett Baier of pushing "fake news" after a poll by the network showed Trump faring poorly against five prominent Democrats.  

"@FoxNews Polls are always bad for me. They were against Crooked Hillary also. Something weird going on at Fox. Our polls show us leading in all 17 Swing States," tweeted the president Monday.

He went on to claim that he did not spend 30 hours with ABC News' George Stephanopoulos for an interview broadcast in full Sunday night, which ABC claimed and Baier had also reported.

"More Fake News," wrote the president in the message directed at Baier. 

Fox's poll published Sunday says that Trump is currently trailing each of the top five Democratic presidential contenders in a hypothetical match-up, and would lose to Democratic front-runner Joe Biden by ten points. 

It is not clear what he meant by "our polls". Recent internal Trump campaign polling showed him trailing Biden in several crucial states, and only narrowly ahead in the traditionally red state of Texas. 

Trump's 2020 campaign fired three pollsters after the data was leaked to the media.

Surprising many, Trump has in recent weeks launched into a series of attacks on Fox News - a network that provides a steady, though not unbroken, stream of positive coverage for his administration. Its top-rated host, Sean Hannity, is a friend and ardent supporter.

In May Trump attacked the network for hosting his Democratic rivals for the presidency.

"They're putting more Democrats on than you have Republicans. Something strange is going on at Fox. Something very strange," Trump told supporters at a rally in Pennsylvania. 

In April, he lashed out at the network for hosting Senator Bernie Sanders of Vermont.

Former White House officials told Politico that Trump has become so accustomed to being praised by Fox network hosts that he has become hyper-sensitive to coverage that could be interpreted as critical. 

While running for the presidency in 2016, Trump became embroiled in a high profile public battle with Fox News, after he was questioned about his attitudes to women by former anchor Megyn Kelly.
