BEIRUT (AP) — Ex-Nissan boss Carlos Ghosn has sat before French investigative judges in Beirut who questioned him for several hours over suspicions of financial misconduct. His defense lawyers said Monday was “a very important day” for the auto magnate-turned-fugitive who is fighting to clear his name. The questioning began at the Palace of Justice in Beirut and was attended by members of the Lebanese judiciary and is expected to last several days. The subjects of multiple investigations in France involving Ghosn’s actions as the head of the Renault-Nissan car alliance include lavish parties in Versailles, questionable payments to an Omani car dealer and suspected tax evasion.
