Mark Cuban, the billionaire businessperson, said he had tried to arrange a private meeting between Elon Musk and Harris, the US vice-president, but Mr. Harris's team had refused. Mr. Cuban said the meeting had failed because "they thought Musk couldn't keep the conversation private." "What he said about Halisra is so off the mark, I think it would be good for them to talk," Mr. Cuban said of Mr. Musk. Mr. Cuban said he would still try to arrange a conversation between Mr. Harris and Mr. Musk if he won the election because he was one of the "best entrepreneurs", adding that the move was "not political, but common sense".
