Joshua Claybourn

Citing Article 1, Section 2 of the United States Constitution, Claybourn appeared before the Indiana Election Commission and successfully challenged a 23-year-old person's legal right to appear on the ballot as a candidate for Congress in Indiana's 8th congressional district.

Together with Abby DeMare, he argued in the Indiana Law Review for greater checks and balances on executive branch emergency powers.

Claybourn served as co-counsel in a civil suit against the State of Indiana and Indiana Governor Eric Holcomb, alleging that Governor Holcomb exceeded his authority under the Constitution of Indiana when he issued certain executive orders in connection with the COVID-19 pandemic.

Citing Governor Holcomb's rescission of the subject executive orders, the trial court dismissed the complaint as moot and the Indiana Court of Appeals affirmed.

Claybourn is considered one of the foremost living scholars of President Lincoln’s youth in Indiana.

He appeared as an expert in the six-part CNN documentary Lincoln: Divided We Stand. Claybourn is editor of Abraham Lincoln's Wilderness Years, a compilation of significant scholarship from J. Edward Murr covering Lincoln's youth.

He is co-editor (with William Bartelt) of Abe’s Youth: Shaping the Future President, providing source material from the Indiana Lincoln Inquiry.

Claybourn also served as a research assistant to Professor Gerard Magliocca during his work on Andrew Jackson and the Constitution: The Rise and Fall of Generational Regimes.

Joshua Claybourn (born June 10, 1981) is an American attorney, author, and historian considered one of the foremost living scholars on Abraham Lincoln’s youth in Indiana.

Claybourn is an attorney with the law firm of Jackson Kelly, representing governmental entities and officials, as well as businesses and corporations.

He was cited as a "key supporter" of Congressman Larry Bucshon of IN's 8th congressional district and was a principal adviser to Evansville Mayor Lloyd Winnecke's campaign and was a part of Winnecke's 2012 transition team.

In 2016, Claybourn was selected as an Indiana delegate to the 2016 Republican National Convention, but a day after Donald Trump's win in the Indiana primary which made Trump the party's presumptive nominee, Claybourn was one of the first to resign his position as a delegate because he "could not in good conscience attend a coronation and celebration of Donald Trump".

The New York Times noted Claybourn would have been bound to vote for Trump on the first ballot.

Claybourn edited Our American Story: The Search for a Shared National Narrative (Potomac Books, 2019), a collection of essays by theorists, historians, and politicians addressing the possibility of a shared narrative within a country divided by political polarization.

Contributors to the project include Cass Sunstein, Gordon S. Wood, John Danforth, Richard Epstein, David Blight, Markos Moulitsas, Alan Taylor, Eleanor Clift, Jim Banks, Nikolas Gvosdev, Ilya Somin, Cherie Harder, Gerard Magliocca, Jason Kuznicki, Cody Delistraty, Spencer Boyer, Ali Wyne, and James Wertsch.

Kirkus Reviews wrote that the book's "responses are all over the map, provocatively so" and called it a "mixed-bag collection".

Claybourn, named one of the 250 most influential leaders in Indiana, often serves as a political advisor.
