Elon Musk, leaning on Skadden, Arps, Slate, Meagher & Flom for legal advice, struck a deal on Monday to buy Twitter, which turned to Wilson Sonsini Goodrich & Rosati and Simpson Thacher & Bartlett for its own legal counsel.

A statement on Monday about the deal did not mention other law firms.  Musk's battle for Twitter started with an SEC filing on April 13 with McDermott, Will & Emery.
