Linda Yaccarino, the chief executive of X, has quit the company.

The shock move came after just two years after she joined the social media platform, and she did not give a reason for stepping down. 

Yaccarino announced the news in an X post, thanking Elon Musk for entrusting her with ‘the responsibility of protecting free speech’ through the role. 

It comes amid an escalating public feud between X boss Musk and President Donald Trump, after their political alliance dramatically broke down in June. 

Musk, once an ever-present ally to Trump as he headed up the Department of Government Efficiency, splintered from the president after calling his signature legislation ‘insane’. Trump’s ‘big beautiful bill’ was signed into law on Friday.

Announcing her shock resignation on Wednesday, Yaccarino, 61, wrote: ‘When @elonmusk and I first spoke of his vision for X, I knew it would be the opportunity of a lifetime to carry out the extraordinary mission of this company. 

‘I’m immensely grateful to him for entrusting me with the responsibility of protecting free speech, turning the company around, and transforming X into the Everything App.’

Yaccarino’s departure is the latest development during a tumultuous period at X, which was transformed under Musk when he purchased the platform for $44 billion in 2022.

Musk set to work making 75 percent of the workforce redundant, while loosening restrictions on the platform which allowed Trump’s account to be re-instated. 

Advertisers were initially scared away from the platform and the social media company suffered from a decline in ad sales. 

Musk said he had sold X to a private artificial intelligence startup called xAI in March. 

Yaccarino previously served as the chairwoman of global advertising and partnerships at NBC Universal from 2011 to 2023 before joining X.

It comes as Musk also recently launched a new political party to rival the Republicans, called the America Party, as his feud with Trump ramped up.

The former ‘First Buddy’ announced the foundation of the party via X on Saturday. 

It came after he created an online poll on July 4 asking his followers whether to establish the new party.

The results came back 65.4 percent in favor, leading Musk to make the announcement.

‘By a factor of 2 to 1, you want a new political party and you shall have it!’ Musk wrote.

‘When it comes to bankrupting our country with waste & graft, we live in a one-party system, not a democracy.

‘Today, the America Party is formed to give you back your freedom.’

Many had predicted that Trump and Musk’s rosy bromance wouldn’t last long and some pointed to betting markets on when they would turn on each other.

Betters heavily favored a fallout before July 1, 2025, less than six months after Musk joined Trump’s administration as a special advisor.

In just a matter of months Musk went from spending $288 million for Trump’s election campaign, to slinging insults about him online.

The bust up occurred after Musk stepped down from DOGE over Trump’s ‘Big Beautiful Bill’ which ends tax breaks for electric vehicles, which are Tesla CEO Musk’s passion project.

Musk also argued that the bill undercut DOGE’s cost-cutting efforts by increasing the deficit.

The rift deepened after the president rescinded his nomination offer to Musk-ally Jared Isaacman for NASA administrator over donations he made to the Democrats.

Since then Trump and Musk have engaged in public mudslinging against each other.

Musk accused the president of ingratitude and claimed he would have lost the election without him, while Trump branded him ‘crazy’.

Trump recently outed himself as the person who leaked details about Musk’s alleged drug use, according to author Michael Wolff, who penned the eye-popping book Fire and Fury: Inside the Trump White House.

The New York Times reported that during the 2024 presidential campaign, the billionaire used so much ketamine he was having bladder problems and also used Ecstasy, psychedelic mushrooms and what appeared to be Adderall.

Musk has denied The Times’ reporting and released a drug test online since.
