Welcome to Rabbit Hole, a breaking news analysis that helps you get smart on the one story everyone’s obsessing over—for Beast Inside members only.

House Judiciary Chairman Jerry Nadler wants to know everything Special Counsel Robert Mueller knows, so he sent basically everyone in Trump’s orbit a letter telling them to cough up what they’ve given federal prosecutors. Welcome to the Congressional version of the special counsel’s investigation, where the witnesses are more public and presumably their evidence will be as well. But can subpoena power help House Democrats dig up or at least make public something that other investigations haven’t already found?

Cut and paste: With 81 recipients of production requests on multiple topics announced today and more on the way, that certainly seems like a lot of investigative work. But look closer and you can see the committee is focused on just a handful of threads. The document requests in the letters are cut and pasted from a handful of lines of inquiry, none of which are news to keen observers of the Russia investigation.
