What's the Difference Between Discovery and Mediation in Federal Litigation?

In June, I said publicly that I'm not going to settle this case unless Twitter essentially agrees to turn over all the third party discovery. And lo and behold, a month later, I did settle the case. The White House was asking for my head on a platter in April 2021,. Now, what do I do next? Well, I can't sue Twitter again. But I can now bring a claim directly against the White House."
