Tesla Inc. founder Elon Musk said he’s working with Wachtell, Lipton, Rosen & Katz and Munger, Tolles & Olson to move forward his proposal to take the electric car maker private. Meanwhile, Tesla’s board of directors has also retained Wilson Sonsini Goodrich & Rosati and Latham & Watkins to evaluate the chief executive’s bid.

After facing a series of questions over possible funding sources for such an effort, Musk has signaled that he remains serious about pursuing the potential buyout, announcing via Monday evening tweet that he is working with financial advisers from The Goldman Sachs Group Inc. and private equity firm Silver Lake Partners, with Wachtell and Munger Tolles serving as outside legal advisers on the proposal.
