Susan Rice is one of few prospective VP nominees who has spoken out about her potential for the position.
In an interview this week she said she was “honoured and humbled” to have a place on Mr Biden’s shortlist.
She signalled her willingness to serve for her country in an interview with NPR’s Morning Edition, saying: “I think I could bring my experience of almost now 20 years in the senior levels of the executive branch to bear to help tackle the most pressing problems we face.
The two-time Democrat administration veteran and former White Houe Security Adviser added: “I’ve been blessed to have served already at the highest levels.
“But if at a time when we are suffering domestically and internationally, people with skills and experience are asked to come back, my judgment is they should say yes, even if it may not be the best thing for them personally.”
