Update in Mueller case: Secret entity trying to defy grand jury (VIDEO)

There is a whole lot of secrecy in Special Counsel Robert Mueller's investigation.

We cannot stress enough that we simply don't know everything yet.

After a judge shut down an entire court house floor in a case that many legal experts are suggesting is linked to the Mueller probe, which is atypical since just the courtroom is usually shut down in such situations, we now have information that there is a secret entity trying to defy a grand jury subpoena.

Now - a federal appeals court has ordered an unidentified foreign company to comply with the investigation, believed to be Mueller's.

Watch MSNBC's Ari Melber talk about the breaking news as it happened.

Some background info: Mueller's team was seen arriving at the U.S. Court of Appeals for the District of Columbia Circuit just last week to reportedly argue about a grand jury subpoena. That's why people think the two developments are related.

Right now we do not know the name of the company - but it has been confirmed that the company was owned by a foreign government.

We will update this article as more information becomes available.
