Idk if anons already discussed that, but I'm thinking the mysterious foreign company asking SC to quash Mueller's subpoena might be Huawei. They recently hired American lawyers: https://www.wsj.com/amp/articles/huaweis-new-play-book-in-washington-drop-pr-and-hire-lawyers-11545047671

We know that they (chinese gov.) were spying, were they actually spying on WH?
