Lindh Sentencing

The American Taliban is due in court Friday, where he's expected to be sentenced to 20 years in prison.

It's part of a plea deal John Walker Lindh worked out with the government -- in exchange for information about former Taliban colleagues and about possible future al-Qaida attacks.

The government said Lindh has fulfilled his agreement to cooperate, undergoing an extensive interrogation as part of a plea agreement.

Many details of Lindh's interrogation remain secret.
