(Reuters) - Tesla Inc
Tesla did not immediately respond to a request for comment, while DoJ declined to comment.
Federal prosecutors opened a fraud investigation over Musk's tweets in early August that he was contemplating taking Tesla private and had "funding secured" for the deal, the report said.
Musk stunned investors last month with tweets saying he wanted to take the electric car company private in a buyout valued at $72 billion (54.70 billion pounds), before backing off.
The billionaire' s behaviour has raised concerns about his corporate leadership, with several Wall Street analysts and some investors urging Tesla to appoint a strong second-in-command. Musk has admitted to severe stress from running Tesla.
The U.S. Securities and Exchange Commission has already opened an inquiry into Musk's tweets.
Shares of the company fell 6.2 percent to $276.
