In his new book, Duty: Memoirs of a Secretary at War, former Secretary of Defense Robert Gates criticizes President Obama’s lack of commitment to U.S. military operations in Afghanistan, and also questions Vice President Biden’s foreign policy skills.

Sen. Jeff Flake (R-Ariz.) questions the timing, calling the release of the book “extraordinarily bad timing, and form, if you ask me.” As it turns out, no one did ask him.
