Nadia Yassir

Nadia Yassir was an agent working at CTU Los Angeles during the events of Day 6.

Before Day 6
Before joining CTU Los Angeles, Nadia was the Director of Intelligence at CTU Detroit and an Intelligence Agent for Middle East Territories with the CIA, eventually becoming a "Senior Intelligence Agent". Nadia was fluent in Arabic, having received a Bachelor of Arts in Language from the University of Michigan. While working in Detroit, Nadia was honored with a commendation from the CIA for her work in penetrating Arab terrorist cells.

At one point, she left open the Jarvis firewall on the CTU database. Chloe O'Brian fixed this, saving Nadia from dismissal from her position at CTU. This was later used as blackmail by Chloe to find out more information about Jack's condition prior to his return.

Day 6
As Day 6 began, Nadia worked at the CTU office coordinating analysts and was the CTU Chief of Staff. She kept Chloe O'Brian from knowing that Jack Bauer was being returned from the People's Republic of China and was being handed over to Abu Fayed in exchange for information leading on the location of Hamri Al-Assad.

Later, as Morris O'Brian and Chloe redirect a satellite and almost jeopardize a mission, Nadia chastises them and gets them to redirect the satellite in the nick of time. She was also seen talking to Fayed on the phone and right before they hang up, she says quietly in Arabic, "Where's your honor?"

Later in the day, White House Chief of Staff Thomas Lennox issues a bulletin stating that all Government employees with a Muslim background is flagged by the Department of Homeland Security, which severly limited her capacity to work. She brought the issue up to Bill Buchanan, who relayed it to Milo Pressman. Milo logged her on to the CTU servers using his username. She was touched at the gesture.

Background Information and Notes
Nadia is a registered Republican, which makes her the only character to date outside of political office holders and their families to have her political affiliation made known on the show.
