Former Florida Gov. Jeb Bush has a deal with publisher Simon & Schuster to release a book next spring, the AP reports. The book’s working title: “Immigration Wars: Forging An American Solution.” It is to be co-authored by conservative attorney and activist Clint Bolick.

Drawing upon history and American ideals, Jeb Bush and Clint Bolick outline a courageous and comprehensive strategy to bridge the partisan divide and set our nation’s immigration policy on a just and rational course,” Threshold said in a statement. “The book will present a comprehensive solution based on two core principles: Immigration is vital to America’s future, fueling its growth, vibrancy and creativity; yet any true and enduring solution must adhere to the rule of the law.”

Bush has been one of the most outspoken advocates for immigration reform in the Republican Party, often pushing for a more inclusive tone from the GOP on the issue.

During an interview on Meet the Press in late August, Bush said, “we have to change not necessarily our core beliefs but the tone of our message and the intensity of it, for sure.” He added, “You can’t ask people to join your cause and then send a signal that you’re really not wanted.  It just doesn’t work.”
