When I said everything in the news comes back to Fed Courts, I was not kidding.
The Second Circuit ordered the district court to redo its analysis of whether President Trump had shown good cause for not removing his New York criminal case under § 1442(a) until just prior to sentencing. Trump claims that Trump v. US (the immunity decision) offered a new ground for removal and thus excuses any delay. The case offers a nice summary of § 1442 and § 1455 and how criminal removal works.
