For one thing, Mueller did that on behalf of the US government and there was nothing secret or illegal about it, it was due to a confiscation they made from smugglers.
For another thing, what does that have to do with criminal activity of others? If something happened to the special council they would get a replacement and the investigations would still move forward. I'm shocked (no not really shocked) that you would dedicate the thread as a whataboutism.
Another question where is your bipartisan skepticism that you claim to have? Do you believe everything you read or only things that look bad for Democrats? I couldn't even find what party Mueller is, they call him apolitical.
Anyhow thats news from like a year ago, whats happened of it since?
