Rudy Giuliani has been warning the press that the president may not testify in the Russia investigation, but Trump has signaled otherwise. This week, we untangle the White House’s mixed-up messaging on the Russia investigation. Plus, after reports that companies like Amazon and Google are seeking, or have received, massive contracts with the Pentagon, we take a look at the internet’s forgotten military origins. And, a new book re-imagines major moments in athletics history.
