Elon Musk's biographer Seth Abramson has claimed that the Tesla CEO is not healthy mentally and that his decision-making and actions could have dangerous implications for the United States.

In a series of posts on X, a platform owned by Musk, Abramson alleged that Musk may be "going mad" and called for immediate government intervention.

Abramson, who claims to have closely followed Musk's behaviour for two years, cited the billionaire's acknowledged struggles with mental health, drug use, and stress.

"I'm a Musk biographer who has been tracking his online behavior for the last two years - and given that he's admitted to all of mental illness, heavy drug use, and crippling stress, it is now reasonable to fear he is deeply unwell," Abramson wrote. "Protect America from Elon Musk."

He said that his private struggles would not be of general concern "except they have dramatic public consequences".

"His holdings across many civilization-essential industries and the fact that he's the incoming POTUS mean that his madness and increasing  incitement of violence endanger us all," Abramson said.

He called upon the US administration to take an urgent call to "protect" the country from Elon Musk.

Musk has been increasingly vocal on X, making polarising statements. Recently, he criticised the UK government for rejecting calls for a public inquiry into a grooming scandal in Oldham and accused UK Prime Minister Keir Starmer of failing to prosecute perpetrators during his tenure as Director of Public Prosecutions.

Musk called these incidents a "massive crime against humanity."
