Al Qaeda scumbag Adam Gadahn (who converted to Islam at the Islamic Society of Orange County) has been indicted for treason, the first person to be so charged since the 1950s.

LOS ANGELES - The charge of treason was used for the first time in the United States’ war on terrorism Wednesday, filed against a California man who appeared in propaganda videos for al-Qaida.

Adam Yehiye Gadahn, 28, could be sentenced to death if convicted of the charge, which has been used only a few dozen times in U.S. history and not at all since the World War II era. He also was indicted on a charge of providing material support to terrorists.

Gadahn “knowingly adhered to an enemy of the United States, namely, al-Qaida, and gave al-Qaida aid and comfort ... with intent to betray the United States,” according to the indictment, handed up by an Orange County grand jury.
