Oh of course, 100%

However when it comes to visa cancellations, from what I understand one is at the mercy of the port of entry officials. Any re-entry with that kind of a visa can trigger a review and the visa may be cancelled for a variety of reasons, not all criminal or proven criminal. I am not saying that's bad or good, it's just how the system works.

The next step is the person usually has to exit the US and re-apply for a visa. So procedurally she should have been put on a plane to Russia. But knowing what Russia looks like they asked her if she should be threatened there so she ended up in a detention center instead.

Like I mentioned in another comment, this was huge mistake from her employee to 1) send her any where, re-entries with these visas should be minimized, especially these days 2) asked her to bring any embryos or any such things.
