Alias, Season 3

Lauren:
Under authority of the National Security Council, Robert Lindsey has instructed me to relieve you of duty as director of this task force until he arrives to assume control.

Dixon:
On what grounds?

Lauren:
Obstruction of justice. Willingly conspiring to impede an international investigation into the murder of Andrian Lazarey.

...

Lauren:
These premises are to be locked down until Lindsey arrives with Federal Agents. That means, until such time, nobody leaves.

Dixon:
I take it you have Sydney in custody.

Lauren:
Not yet. But we know where she is.
