"The Hill to Die On" is about to be everywhere.

Jake Sherman and Anna Palmer's scoop-filled book about Capitol Hill in the Trump age comes out next Tuesday, and it's already starting to make news. WaPo's Ashley Parker says the book reads like an extended edition of Sherman and Palmer's Politico Playbook newsletter, with each chapter containing "at least one or two nuggets."

President Trump, Mitch McConnell, Paul Ryan, Nancy Pelosi, Chuck Schumer, and Mark Meadows were all interviewed on the record. I peeked at the book's notes on sourcing... It says the authors interviewed "characters in this book and aides involved in the legislative process as often as sev¬eral times each week stretching from Election Day 2016 through Febru¬ary 2019."

And check this out: "On several occasions, sources allowed us to listen in to telephone conversations or conference calls as they were happen¬ing."Plus: "Sources in both parties agreed to share meeting notes, transcripts of telephone conversations, recordings of telephone conversations, and recordings of meetings, e-mails, and memos."
