The son of an ex-CIA spy has pleaded guilty to conspiracy after admitting he met with his father's former Russian handlers and accepted money from them.

Nathaniel Nicholson entered guilty pleas Thursday to conspiracy to act as an agent of a foreign government and conspiracy to commit money laundering.

Federal prosecutors said the younger Nicholson traveled around the world taking cash from agents of the Russian Federation, who were trying to find out how much ex-CIA agent Harold "Jim" Nicholson had told U.S. investigators.

Jim Nicholson, an Oregon native, was the CIA's chief instructor in spy "tradecraft" when he sold information on the agents he was training to the Russians. He was convicted in 1997 and sentenced to 23 years in prison.
