Sen. Mazie Hirono of Hawaii, the Senate's first Asian-American woman and only current immigrant, is working on a memoir.
Viking announced Tuesday that the book, currently untitled, will come out in 2021.
Hirono, 72, will write about emigrating at age 8 to the United States after her mother fled an abusive marriage in Japan. In a statement issued through Viking, Hirono said the book was a tribute to her mother's spirit and a chance "to bear witness on her behalf by telling the story of the daughter she inspired to live boldly."
Hirono, a Democrat, made news last year as a leading critic of Supreme Court nominee Brett Kavanaugh, who faced allegations of sexual harassment and attempted assault. Kavanaugh, who was narrowly confirmed, denied the allegations.
