John Walker Lindh to be released but some politicians say he may still be security risk

John Walker Lindh, the American captured in 2001 fighting for the Taliban, is to be released early from federal prison despite some US politicians expressing concerns he may still be a security risk.

Lindh, photographed as a bearded 20-year-old when captured in Afghanistan, will leave a federal prison in Terre Haute, Indiana, on probation on Thursday after serving 17 years of a 20-year sentence, according to a prison official.
