As the New York Post noted earlier in the week:
In court papers filed last month, Durham said the Democratic National Committee, Hillary for America, the Fusion GPS research company and the powerhouse Perkins Coie law firm — where Sussmann was formerly a partner — “have all withheld and/or redacted documents and communications” that could potentially be used against the defendant.”
Durham said they made that decision “based on an apparent theory that political opposition research and/or public relations work … falls within the legitimate scope of attorney-client privilege and work-product protections.”
“They have done so despite the fact that almost all of these materials appear to lack any connection to actual or expected litigation or the provision of legal advice,” members of Durham’s team wrote.
