NEW YORK (AP) — The White House speechwriter who helped President Barack Obama work on his response to the Charleston church massacre in June 2015 has a book deal. Cody Keenan’s memoir is called “Grace.” It is set around the time a white supremacist murdered nine Black parishioners in South Carolina. Publisher Houghton Mifflin announced Tuesday that “Grace” will be published in fall 2022. The book’s title refers to a theme of Obama’s response to Charleston and one of the most emotional moments of his presidency. He sang “Amazing Grace” during his eulogy for one of the Charleston victims, the Rev. Clementa Pinckney.
