Mueller Testimony Frustrates Both Parties by Rarely Straying From His Report Masood Farivar WASHINGTON - "I'll refer you to the report on that." "That's accurate based on what's in the report." "I don't want to wade in those waters."

He stuck to his word, frustrating both Democrats and Republicans in the process. .
