On Thursday I asked that President Obama no longer consider me for the job of secretary of state. I made this decision because it is the right step for this country I love. I have never shied away from a fight for a cause I believe in. But, as it became clear that my potential nomination would spark an enduring partisan battle, I concluded that it would be wrong to allow this debate to continue distracting from urgent national priorities — creating jobs, growing our economy, addressing our deficit, reforming our immigration system and protecting our national security.

These are the issues that deserve our focus, not a controversy about me. On Sept. 16, when Secretary of State Hillary Clinton was unavailable after a grueling week, the White House asked me to appear on five Sunday talk shows to discuss a range of foreign policy issues: the protests against our diplomatic facilities around the world; the attack in Benghazi, Libya; and Iran’s nuclear program.
