As has been widely reported, for instance here, Judge Kimba Wood recently required Michael Cohen to reveal his client list in open court during the legal proceedings surrounding his prosecution via the crime-fraud exception to attorney-client privilege. Notably, this has caused significant embarrassment for Sean Hannity, an otherwise secret member of this client list.
So far as I am aware Wood's ruling is perfectly consistent with the law: attorney-client privilege protects communication between a client and his or her lawyer but it does not protect the fact that such communication occurred. Nevertheless Wood could have chosen to require Cohen to reveal his client list to prosecutors privately, and I am wondering how much precedent there is for instead requiring that the disclosure occur publicly.
Are there other examples where an attorney prosecuted under the crime-fraud exception to attorney-client privilege was required to reveal his or her client list in open court?
I can't claim I am personally concerned a great deal for Hannity's reputation, but the case has much broader significance and I am trying to understand the context as thoroughly as possible.
As pointed out in the comments, this question is quite similar to another question. The answers to that question did not answer mine because I was already convinced of the legal justification for publicizing the client list and I am specifically interested in precedents / case studies - the current answer to this question is exactly what I had in mind. But the similarities are undeniable and I am new to this forum, so I leave the decision to mark this as a duplicate to the existing community.
