Donald Trump has backtracked over a series of scathing tweets he wrote about President Obama as he secured a second term last night - hastily deleting messages calling for a 'revolution'.
And when NBC's Brian Williams lambasted Trump's Twitter tantrum on his show, the outspoken business mogul turned his anger on the host and his 'boring' newscasts.
Trump took to the social networking site after the president's victory was projected by several news outlets on Tuesday night, and claimed the re-election was a 'great and disgusting injustice'.
After a barrage of outraged messages, Trump added: 'He lost the popular vote by a lot and won the election. We should have a revolution in this country!'
Minutes later, he deleted the tweet - perhaps aware of the potential legal ramifications of a remark seeking to incite a revolution against the president.
NBC's Brian Williams read some of Trump's tweets on the air, while claiming he did so reluctantly, as he declared that the TV personality - whose show, Celebrity Apprentice, airs on NBC - had 'driven well past the last exit to relevance.'
'This is, as they say, out there and getting an airing tonight, so you might as well know about it,' Williams groaned. 'Donald Trump, who has driven well past the last exit to relevance and veered into something closer to irresponsible here, is tweeting tonight. Here's a sampling...'
Williams read several of Trump's tweets, which called the election a 'total sham and a travesty.'
However, as it became apparent that former Massachusetts governor Mitt Romney would not win the election, the Donalds tweets became more enraged, and more hyperbolic.
Trump began with: 'Well, back to the drawing board!'
He quickly followed up with a call to revolution. The Trump wrote: 'He lost the popular vote by a lot and won the election. We should have a revolution in this country!' - before deleting the tweet.
But he was far from over. 'This election is a total sham and a travesty,' he wrote. 'We are not a democracy! He added America is in 'serious and unprecedented trouble like never before'.
