Our intrepid heroine begins season six working with President-elect Keane's team as a secret foreign policy advisor. But she quickly becomes embroiled in uncovering a plot by Dar Adal to frame a Muslim man for an explosion in New York and plant evidence that Iran has violated its nuclear agreement with the US.
It escalates into an assassination attempt on Keane for which Quinn is going to be framed. Carrie is able to stop the assassination attempt, but Quinn dies in the process. After Keane is sworn in as president, Carrie works for her administration as a liaison to the intelligence community. She is offered a permanent advisory position but turns it down once she learns Keane has ordered the arrests of 200 innocent intelligence officers from the State Department, Department of Defense, and CIA — including Saul Berenson.
