Elon Musk fired back at former US President Donald Trump, saying on Monday it is time for Trump to "hang up his hat and sail into the sunset," Reuters reports.

Musk’s comments came days after the former US President mocked the billionaire at a political rally and called him a "bulls--- artist."

Writing on Twitter, Musk said, "I don't hate the man, but it's time for Trump to hang up his hat & sail into the sunset."

"Dems should also call off the attack – don't make it so that Trump's only way to survive is to regain the Presidency," he added without explanation.

He also wrote that if Florida Governor Ron DeSantis ran against President Joe Biden in 2024, "then DeSantis will easily win" and that "Trump would be 82 at end of term, which is too old to be chief executive of anything, let alone the United States of America."

Musk's remarks were a response to comments Trump made at a rally in Anchorage, Alaska on Saturday, where he was speaking in support of US House of Representatives candidate Sarah Palin and US Senate candidate Kelly Tshibaka.

Trump said at the time that Musk was not going to buy Twitter and that the Tesla chief executive had got himself a mess.

"(Musk) said the other day, I've never voted for a Republican. I said I didn't know that; he told me he voted for me. He's another bulls--- artist, but he is not going to be buying it (Twitter)," Trump said.

Trump’s comments came a day after Musk announced that he was backing out of a deal to buy Twitter for $44 billion, accusing the social media giant of failing to make good on a promise to give him access to information about spam accounts.

The back-and-forth between the two came despite the fact that they appeared to be on good terms just several months ago.

Shortly after Musk announced his bid to buy Twitter, he said that in his opinion, it was a mistake to ban Trump from the platform and would restore his account.

Trump, for his part, indicated that he will not return to Twitter even if his account is reinstated following the platform's purchase by Musk.
