Billionaire Elon Musk has suggested he will step up to the mark if appointed to a White House role by Republican presidential candidate Donald Trump. 

Trump said yesterday if he is elected president in November he would be open to naming the Tesla CEO to a cabinet or advisory role. 

'He's a very smart guy. I certainly would,if he would do it,I certainly would. He's a brilliant guy,' Trump said in an interview with Reuters. 

Musk responded to the comments on X today with just five words: 'I am willing to serve.' 

The CEO of X,formerly known as Twitter,also shared a picture of himself standing behind a podium with the words 'Department Of Government Efficiency' and 'D.O.G.E etched onto it. 

The sign appears to be a reference to Dogecoin,a joke cryptocurrency that Musk aggressively promoted in 2021 causing its value to soar. 

Trump appeared to enjoy the chat (pictured) where he laid into Kamala and Mr Musk joined in

'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.'
