Musk and Trump have already formed an alliance with the Tesla CEO publicly endorsing Trump in the presidential race.

The pair carried out an extraordinary online interview together last week that was beset with problems including a major delay because of a ‘massive’ cyber attack.

The interview was also dominated by listeners noticing that Trump appeared to have a lisp or even slurred his words at points, struggling with words containing ‘s’ sounds.

The interview on X started 45 minutes late after the social media site’s servers were hammered with a Distributed Denial of Service (DDoS) attack.

Once up and running Trump spoke about becoming more religious after the attempt on his life in Pennsylvania on July 13, a shooting that Musk said showed Trump’s courage.

The 45th President of the United States also vowed to build an ‘Iron Dome’ defence system for America like the one used by Israel to intercept missiles.

He then promised he would oversee the largest deportation of illegal immigrants in history if he became president in November, insisting that cities like New York have been ‘overwhelmed’ and that ‘rough people’ including terrorists are entering the US from Mexico.

‘These are people that are in jail for murder and all sorts of things, and they’re releasing them into our country,’ he said.

Mr Musk then urged Americans to vote for the Republican presidential nominee over Kamala Harris, saying that the US is at a ‘crossroads’ and that choosing Trump would be a vote for hope and prosperity.

In return Trump said he had ‘no choice’ but to back electric vehicles ‘because Elon endorsed me very strongly’. Previously he said that EV supporters should ‘rot in hell’.

However, Trump said on Monday that if he is elected he would consider ending a $7,500 tax credit for electric-vehicle purchases.

‘Tax credits and tax incentives are not generally a very good thing,’ Trump told Reuters in an interview after a campaign event in York, Pennsylvania, when asked about the EV credit.

‘I’m not making any final decisions on it,’ he added.

‘I’m a big fan of electric cars, but I’m a fan of gasoline-propelled cars, and also hybrids and whatever else happens to come along.’
