US House Panel Launches Investigation of Transportation Chief Chao Reuters WASHINGTON - A U.S. House of Representatives panel on Monday demanded documents from Transportation Secretary Elaine Chao as part of a new investigation into whether she has used her office to benefit a shipping company owned by her family.
