Sean Hannity has launched a passionate defense of Fox News' co-president Bill Shine amid speculation his time at the network could be coming to an end.

The polarizing host fired off a series of tweets on Thursday afternoon amid rumors Shine was potentially losing support from the Murdochs - particularly James and Lachlan.

New York Magazine cited a source close to Shine - who has been with Fox News since its inception - as saying he is 'expressing concern about his future at the network.'

The magazine's writer, Gabriel Sherman, claimed in the piece James and Lachlan Murdoch have refused to publicly back Shine.

They also ignored his request to release a statement supporting him.

Responding to the article, Hannity tweeted at Sherman: 'Gäbe i pray this is NOT true because if it is, that's the total end of the FNC as we know it. Done. Best Sean.'

The host then continued to discuss the story, even going as far as to claim Shine was being sabotaged by someone within Fox News.

'Somebody HIGH UP AND INSIDE FNC is trying to get an innocent person fired. And Gabe I KNOW WHO it is. Best Sean.

'I'll change it. #Istandwithshine.'

Shine was elevated to the position of co-president after Roger Ailes was ousted last year.

He is also one of the executives named as a defendant in former host Andrea Tantaros' lawsuit claiming she was, 'sexually harassed by Ailes and Bill O'Reilly... through illegal electronic surveillance.'

That 'surveillance' according to the filing involved 'the hacking of her personal computer' and 'the use of "sockpuppet" social media accounts to stalk Ms. Tantaros.'
