I want to know the answer to the following question:
Who backed out of becoming SoS after Hillary?
All the background I'm provided with is that "On December 15, 2012, several news outlets reported that President Barack Obama would nominate Kerry to succeed Hillary Clinton as Secretary of State, after Susan Rice, widely seen as Obama's preferred choice, withdrew her name from consideration citing a politicized confirmation process following criticism of her response to the 2012 Benghazi attack.". Is that enough to answer the question?
Answer: yes
