YONKERS - Former Secretary of State Hillary Clinton's new book, entitled "Hard Choices," is scheduled to be released Tuesday.

Clinton sat down with ABC News to talk about everything from the book, including her health and a possible run for the White House.

During the interview with ABC's Diane Sawyer, Clinton also addressed the 2012 terrorist attack in Benghazi and said she hasn't ruled out testifying before a Republican-led House committee.

Additionally, Clinton discussed the millions of dollars in speaking fees she and her husband, former President Bill Clinton, have amassed since becoming private citizens in Chappaqua.

Her first book signing will take place Tuesday at the Barnes & Noble in Union Square.

"Hard Choices" has already pre-sold 1 million advance copies. Sources close to Clinton say she is hoping to surpass her first book, which sold 40,000 copies on its first day.
