[JURIST] A federal grand jury on Wednesday indicted [press release] Adam Gadahn [ABC profile], a US citizen accused of aiding al Qaeda, on charges of treason and providing material support to a foreign terrorist organization. The indictment [PDF text] marks the first treason charges to be brought against a US citizen in over half a century. The DOJ alleges that Gadahn attended al Qaeda-run terrorist training camps in Afghanistan and that he threatened attacks on the US while appearing in multiple videos distributed by al Qaeda between October 2004 and September 2006. At this time Gadahn is not in US custody and his location remains unknown.
The Federal Bureau of Investigation (FBI) [official website] has been seeking information [FBI listing] on Gadahn since May 2004. Last month, he appeared in a video with al Qaeda second-in-command, Ayman al-Zawahri [CNN profile], in which Gadahn said that the US should "enter into the light of Islam." AP has more. Reuters has additional coverage.
