Sen. Josh Hawley is writing a new book calling for a religious revival in America

• Josh Hawley is writing his fourth book — while running for a second term in the Senate.
• It's called "The Awakenings: The Religious Revivals that Made America—and Why We Need Another One."
• The Missouri senator has written books about masculinity, Big Tech, and Theodore Roosevelt.

Sen. Josh Hawley is running for reelection this year. He also happens to be in the middle of writing a new book.

The Missouri Republican is working on a new book entitled "The Awakenings: The Religious Revivals that Made America — and Why We Need Another One," his publisher confirmed to Business Insider on Tuesday.

A spokesperson for Hawley did not immediately respond to a request for comment.

Hawley signed the agreement with Regnery Publishing in October 2023 and is set to deliver a manuscript no later than January 2025.

The conservative book imprint has published Hawley's previous two books, including "Manhood: The Masculine Virtues America Needs" in 2023 and "The Tyranny of Big Tech" in 2021.

The latter book was previously set to be published by Simon and Schuster, but the publisher cancelled the deal after Hawley led the objection to Pennsylvania's electoral college results in 2020.

The Missouri senator also wrote a book about President Theodore Roosevelt in 2008, while working as a clerk for Supreme Court Chief Justice John Roberts.

Hawley, who has positioned himself as a future presidential contender while pushing the GOP in a more populist direction, has long been an advocate for Christianity in the United States. His previous book, "Manhood," drew heavily on Biblical references.

In February, Hawley published an essay in the religious journal "First Things" arguing that the United States is a fundamentally Christian nation.

"America as we know it cannot survive without biblical Christianity," Hawley wrote at the time. "The rights we cherish, the freedoms we enjoy, the ideals we love together — all are rooted in and sustained by the tradition of the Bible. Christianity is the electric current of our national life."

The Missouri senator's annual financial disclosure, filed last week, indicated that he made $127,500 from book royalties in 2023. It is unclear whether that sum includes an advance for Hawley's forthcoming book or also includes composed of royalties from the senator's previous books. In 2021, Hawley made $467,000 in book royalties.

Books have long been a way for senators — particularly those with high profiles — to make extra money on the side. In 2022, six senators made more than their $174,000 salaries via book advances and royalties.

That included Democratic Sen. Raphael Warnock of Georgia, who made the largest sum of any senator in 2022 — $655,000 — while also embarking on a book tour months ahead of his high-stakes reelection race.
