The question of why so few Republicans have stepped forward to testify about what they heard and saw in the Trump White House, is very much at the heart of much of the House Jan. 6 committee\u2019s work \u2014 and of Tim Miller\u2019s new book, \u201cWhy We Did It,\u201d which, by chance, was released the same day as Hutchinson\u2019s explosive testimony.\nMiller\u2019s arc is, by now, somewhat familiar: At the dawn of the Trump era, he was an in-demand Republican strategist and a top aide to Jeb Bush. He watched in horror as Trumpism swallowed the Republican establishment and his fellow GOP strategists jumped on the MAGA bandwagon. He resisted, left the party, and devoted himself to Never Trumpism.\nIn his new book, Miller sets out to understand the mindset of those Republicans who remained \u2014 friends and former colleagues who weren\u2019t all that different from him, but who enthusiastically worked to elect Trump and later joined his administration.\xa0\nIn one chapter, he traces the journey of Alyssa Farah Griffin. In 2016, she was a 20-something conservative and top Capitol Hill aide who couldn\u2019t bring herself to vote for Trump. By 2020, she was director of strategic comms in the Trump White House \u2014 before resigning that December.\nOn the outside, Griffin joined Miller in the ranks of the Never Trumpers, and began helping others do the same. Most recently, it was Griffin who helped guide Hutchinson, her good friend, through the fraught process of breaking away from the Trump world, a journey that culminated in Hutchinson\u2019s devastating account of Trump\u2019s actions on Jan. 6.\xa0\nOn Thursday, Ryan met with Miller and Griffin at the Georgetown Club for lunch \u2014 and to talk about Miller\u2019s new book, their respective journeys navigating Trumpism and what Hutchinson\u2019s testimony could mean for the future of Trump\u2019s grip on the Republican Party.\nRyan Lizza is a Playbook co-author for POLITICO.Tim Miller is a political strategist and writer-at-large for The Bulwark.Alyssa Farah Griffin is a political commentator and former Trump White House aide.Afra Abdullah is an associate producer for POLITICO audio.Kara Tabor is a producer for POLITICO audio.Brook Hayes is a producer for POLITICO audio.Adam Allington is senior producer for POLITICO audio.Jenny Ament is executive producer for POLITICO audio.\n\nLearn more about your ad choices.
