This is great news for Tesla. Research a bit about the new lawyer and his firm.
Williams & Connolly LLP is a prominent law firm based in Washington, D.C.. In 2019, it was ranked the most selective law firm in the United States. This new general counsel is the Chairman of Williams & Connolly. The firm has 200~300 attorneys, not a small firm. Everything Elon is setting up is top notch, he will not settle for the second best.
Statement from this new lawyer:
“Tesla’s mission is bigger than Tesla—one that is critical to the future of our planet.”
“It’s hard to identify a mission more timely, more essential, or more worth fighting for”
Statement from the leaving lawyer: “Being part of Tesla for the last five years has been the highlight of my career, Tesla has been like family to me, and I am extremely grateful to Elon, the board, the executive team, and everyone at Tesla for allowing me to play a part in this incredible company.”
I have no clue and also don't care if this news will affect the stock in near term. I expect Tesla to have spectacular growth in the next 3 years, and the next 10 years.
Edit: "In 2019" should be "In 2019 Vault Ranking List"
They are #1 among the most selective law firms;
#1 Best law firms for white collar defense and internal investigations.
