IMF chief Christine Lagarde under investigation in France

Christine Lagarde, the chief of the International Monetary Fund, was placed Wednesday under official investigation for negligence in a French corruption probe that dates back to her days as France's finance minister. In a statement after a fourth round of questioning before magistrates, Lagarde said she would return to her work in Washington later in the day and said the decision was "without basis." She and her former chief of staff face questions about their role in a 400 million-euro ($531 million) payment to a businessman. "After three years of proceedings, dozens of hours of questioning, the court found from the evidence that I committed no offense, and the only allegation is that I was not sufficiently vigilant," she said in her statement.
