Love seeing that readers who read/bought my book also read/bought the books of my friends @mkn.bsky.social @jgienapp.bsky.social and @rachelshelden.bsky.social If you liked Migration and the Origins of American Citizenship, you really will love theirs too.

4/22 webinar: In an era of polarized historical memory, how can colleges and universities teach history in ways that strengthen democratic culture? Join Mary Clark, Suzanne Marchand, Jeffrey Collins, and Hoover's @jgienapp.bsky.social for "Historical Thinking and Democratic Citizenship". RSVP ⤵️

Honestly still in shock by its placement, but my article (and job talk paper), “Indigenous Constitutionalism,” is officially out in the Harvard Law Review. A brief thread on this project🧵 harvardlawreview.org/print/vol-13...

Had a lovely chat this morning with a university physicist who assured me that law professors trying to compare themselves to Einstein and others to Sir Isaac Newton are not even right about their condescending insult.

New at Can We Still Govern?: @unlawfulentries.bsky.social puts yesterday's oral arguments about birthright citizenship into historical perspective, noting how the Fourteenth Amendment took aim at internal migration laws that restricted movement. 🧵 donmoynihan.substack.com/p/rememberin...

Not sure whether this is apt or terrible timing but here’s the official cover of my book due out with @uncpress.bsky.social W. Hodding Carter III imprint this fall. 🎉

After years of research, Daphna Renan & I are thrilled to announce preorders of SUPREMACY. Why is US democracy so broken? One reason is we've wrongly accepted that 9 justices have the final say over the Constitution. This book traces how that happened—& how we can reclaim power to govern ourselves.

His reflections on his life and work, “Things Needed to Get Better,” was just published earlier this year. Rest in peace…

New symposium on my book is out in the Yale Journal of Law & the Humanities! It features essays by an extraordinary group of scholars from across Law and History followed by my response. yaleconnect.yale.edu/yjlh/yjlh-is...

Very interesting paper by philosopher William Ewald in the recent symposium on @jgienapp.bsky.social’s Against Constitutional Originalism. openyls.law.yale.edu/server/api/c... This is a thread for notes about first impressions from my second read through.

Read Jonathan’s response alone to completely change the way you think about the Constitution in the Founding Era!

Folks, my Originalism seminar paper just leveled up in a big way

!!! Not to be missed — including in particular @jgienapp.bsky.social’s response to his critics. Had the chance to teach on this in American Legal Thought this year, and it was a real treat.

Now the symposium is published! bsky.app/profile/jgie...

this, from prof @jgienapp.bsky.social, is the most devastating criticism of originalism i’ve ever read. i truly hope that scholars don’t miss the radical nature of his *conceptual* rupture claim. i look forward to reading the book. papers.ssrn.com/sol3/papers....

See what the Dean doesn’t understand is that I really have two jobs: my job job, and then answering email

Hard to oversell how incredibly good @jgienapp.bsky.social's "The Second Creation" is. Just incredible, subtle, mind-altering constitutional history.

The Supreme Court blocked Trump’s tariffs, but don’t forget: The same Court brought us the anti-constitutional abomination of presidential immunity. www.brennancenter.org/our-work/ana...

University of Michigan: On Friday, come participate in a day-long conference discussing/criticizing my new book *The Oldest Constitutional Question: Enumeration and Federal Power.* With Profs. Jack Balkin (Yale), Maggie Blackhawk (NYU), Sam Erman (Michigan), Jonathan Gienapp (Stanford)… (1/4)

Among the critical points @jgienapp.bsky.social reiterates here is that many early Americans were anti-legalists, but even early lawyers saw the Constitution as different from ordinary law, requiring "a different interpretive style and conceptual toolkit." An important (& highly entertaining) read!

I have been waiting to post about this new essay until the symposium on my book of which it is a part is published (should be very soon!), but until then, you can check out what I have to say in response to some thoughtful esays. Deep thanks to @evanbernick.bsky.social for this generous promotion.

@jgienapp.bsky.social responds at great length to critics of his criticism of originalism. It’s a tour de force. read it. papers.ssrn.com/sol3/papers....

I had a great time taking part in this conversation on originalism in the lower courts with my excellent colleagues, @orinkerr.bsky.social and Jud Campbell. Thanks to Short Circuit for putting together such a terrific event.

I really enjoyed this podcast conversation about originalism in the lower courts, with experts on originalism @jgienapp.bsky.social and Jud Campbell. Thanks to the Short Circuit crowd for having us.

Andrea Katz explained this better than I could/did in this morning’s Times: www.nytimes.com/2026/01/21/o... (Great also to see shoutouts to the work of Historians Council members @jgienapp.bsky.social and @narosenblum.bsky.social)

Tomorrow, SCOTUS is hearing Trump v. Cook, a case involving President Trump’s attempts to remove Lisa Cook from the Fed. It’s a glaring example of the admin's coercive approach to power. And it could pose BIG problems, even if SCOTUS ultimately rules for Cook. Walk with me...🧵⬇️@brennancenter.org

But this “Fed carveout” is bunk, as a historical matter. Historians have also shown that the unitary executive theory is operating in a whole space of dubious history. From @jgienapp.bsky.social: www.brennancenter.org/our-work/res...

For anyone interested in how to confront originalism, this is an invaluable and FREE resource designed by folks who have been leading the fight. Please give this important manual a read and spread the word! @tomtmwolf.bsky.social @sam-breidbart.bsky.social @cisozaki.bsky.social

⏰NEW RESOURCE: In Countering Originalism: A Guide for Litigators, @sam-breidbart.bsky.social, @cisozaki.bsky.social, and I offer lawyers the strategies, arguments, and citations that they need to push back against originalist claims they encounter in court 🧵⬇️ www.brennancenter.org/our-work/res...

Sunstein posted an admirably frank essay yesterday on the Unitary Executive Theory: How he participated in this elite bipartisan political consensus — and how he has been persuaded by overwhelming historical evidence that he & other high-ranking lawyers were wrong. open.substack.com/pub/casssuns...

Council Member @jgienapp.bsky.social joined with Professor Andrea Scoseria Katz for a brief addressing, among other things, the historical evidence unearthed since the Court’s last major removal cases earlier this decade. www.brennancenter.org/media/14714/...

The fall semester has been SUPER busy for the members of the Historians Council on the Constitution. Walk with me through this 🧵for highlights from the historians' work on some of the most pressing legal issues of the day, from agency independence to voting rights... @brennancenter.org

Took about 20 years. And I never thought a book about enslavers using deputization to give themselves policing power would be relevant to our times. But we are where we are. My book, White Power: Policing American Slavery, is now available for preorder. a.co/d/29c7EIP
