IMF chief Lagarde named key witness in investigation of payoff to French business tycoon

IMF chief Christine Lagarde says a Paris court has named her as a key witness in an investigation into a controversial payoff to an outspoken businessman arranged while she was France's finance minister.

The status of "assisting witness" means that Lagarde could later be charged in the case. The court assigned her the status Friday after two long days of questioning in the case.
