Trump says he tried to stop John Walker Lindh's release from prison

President Trump is angry that John Walker Lindh walked out of an Indiana prison on Thursday, telling reporters he was ticked off when government lawyers told him there was nothing they could do to stop Lindh's release.

Lindh, 38, was captured in Afghanistan in 2001 after volunteering to fight with the Taliban. Dubbed the "American Taliban," Lindh converted from Catholicism to Islam at 16, and left his home in California to study Arabic in Yemen. He pleaded guilty in 2002 to supplying services to the Taliban, and during his sentencing, said he never planned on fighting U.S. forces and condemned "terrorism on every level."

Lindh served 17 years of a 20-year sentence, and as part of his release conditions, he cannot communicate with known extremists, have a passport, or use any device that can access the internet without permission from his probation officer. Leaked documents from 2016 show the government believes Lindh still holds "extremist views," and the Federal Bureau of Prisons said in a statement it does have policies in place for monitoring parolees with links to terrorism.

Trump said what bothers him the most is that Lindh "has not given up his proclamation of terror, and we have to let him out. Am I happy about it? Not even a little bit."
