Elon Musk feuds with ex-MSNBC host Keith Olbermann in X post smackdown: 'F--- you fascist'

X owner, billionaire and Trump-appointed co-chair of the Department of Government Efficiency, Elon Musk, got into an online feud with former MSNBC anchor, Keith Olbermann. 

Olbermann started the feud with an obscenity-laced post calling Musk a "fascist," while the billionaire and incoming Trump cabinet member ripped him for having a neurological disability.

Olbermann wrote on Thursday, "So @elonmusk you also suck at politics lol f--- you fascist." 

"You elevate Tourette's to poetry," Musk fired back at Olbermann that evening. 

Musk and other conservatives expressed frustration at many of the bill's provisions they deemed unrelated and unnecessary to a "clean" extension of government funding. The billionaire demanded that members of Congress who planned on voting for the bill get tossed out.

Shortly after Musk posted his reaction to the bill, Trump's presidential transition team released an official joint statement by Trump and Vice President-elect JD Vance opposing the initial iteration of the deal. 

The stiff pushback from these figures caused negotiations between lawmakers on that version of the bill to implode, leaving them scrambling to come up with a new proposal ahead of a looming shut down at midnight on Friday. 

In the wake of Musk's post, liberal lawmakers and pundits have raged against the billionaire, accusing him of tanking the bill, and accusing the GOP of letting the non-elected commandeer the party and meddle in the government process.

Other prominent conservatives on the platform laid into Olbermann.

Conservative actor Matthew Marsden pointed out the irony of Olbermann having an X subscription, writing, "You support him by paying for your blue tick. Hilarious."

Comedian Chrissie Mayr also replied, "I thought you were leaving twitter Keith.
