People who spoke to CNBC about how the White House handled Musk declined to be named in order to speak freely about the private conversations.

“The idea of ​​the feud is not entirely correct.

Public outrage and media pressure around this statement forced him to admit that Tesla is in fact leading the electric car industry. He wouldn’t exactly call that ‘praise’,” he said. Musk in the email on Tuesday.

A White House spokesperson praised Tesla on Tuesday in an email to CNBC: “Tesla has done extraordinary things for electric vehicles and that’s a big part of why the entire industry now knows that electric vehicles are the future.”
