Elon Musk has said that he will not leave US President Donald Trump's Business Advisory Council.
The tech leader is also part of Mr Trump's Manufacturing Jobs Initiative - and last week he attended a meeting of this group with Mr Trump at the White House.
Uber’s CEO Travis Kalanick has stepped away from Mr Trump's advisory group, but Mr Musk will not leave.

He issued a statement on Twitter saying that he and a number of the council's other members would register their opposition to Mr Trump's Executive Order regarding new 'enhanced vetting' procedures.
The Tesla boss added that taking part in the group does not mean that he agrees with the actions of the US president and that he will continue to engage with him regarding ways to promote and develop sustainable energies.
Last Saturday he tweeted that, “The blanket entry ban on citizens from certain primarily Muslim countries is not the best way to address the country’s challenges."
He also retweeted a post saying that new rules are less radical than media reports had suggested, writing that it is better to read the document rather than relying on, "other people's opinions."
