Vice President Kamala Harris has a "powerful" new campaign adviser: her brother-in-law Tony West, the former Obama Justice Department attorney who defended a convicted terrorist sentenced to 20 years in prison for fighting with the Taliban and colluding with al-Qaeda.

West is now "a powerful adviser" to Harris's "new campaign," Axios reported Friday. Roughly 20 years prior, West held a different role: attorney for a Taliban terrorist.

West in 2002 signed on to defend "American Taliban" John Walker Lindh, who was captured in Afghanistan one year earlier and subsequently indicted for providing services to the Taliban and al-Qaeda—and for conspiring to murder Americans. During the trial, West—then an attorney at the San Francisco law firm Morrison & Foerster, which was known for defending enemy combatants detained by the United States—dismissed claims that Lindh was a terrorist.

"He is not a terrorist," West said of Lindh during a 2002 Washington Post interview. "He did not go to Afghanistan to kill Americans." Lindh, who also goes by Sulayman al-Faris and Abu Sulayman al-Irlandi, was later sentenced to 20 years in prison. He has refused to renounce his Islamic extremist ideologies.
