NEW YORK (AP) One of Washington's leading advocates for gun control, Sen. Chris Murphy, has a book coming out next year.

Murphy's ``Violence Inside Us: A Brief History of an Ongoing American Tragedy'' will be published Jan. 20, Random House announced Monday. Murphy, a Democrat from Connecticut, said in a statement that the book was an exploration of the roots of violence and ``a deeply personal journey'' of his own battle against gun violence. His journey begins with the 2012 shootings in Newtown, Connecticut, when a gunman killed 20 first graders and six adults at the Sandy Hook Elementary School.

Murphy added that he hopes his book will lead to a ``fresh, less polarized conversation.''
