In the Roger Stone case, the government said it had turned over 9 terabytes of discovery — an amount so large that Stone's lawyers said if it were on paper, it would pile as high as the Washington Monument, twice, AP reports.

By the numbers: Mueller's evidence is likely massive. His "team issued more than 2,800 subpoenas, executed nearly 500 search warrants and interviewed more than 500 witnesses."

• "That means the special counsel likely compiled thousands, if not millions, of documents and pieces of evidence."
• "Material collected ranges from a $15,000 ostrich jacket worn by [Paul Manafort] to emails and encrypted text messages to hard drives and laptops."
