U.S. Transportation Secretary Elaine Chao has sold her stock holdings in leading aggregates company Vulcan Materials Co., after published reports said Chao—a former Vulcan board member—had owned stock in the company for more than a year after the date when she had said she would divest it.
In a June 12 letter to a senior ethics officer at the Dept. of Transportation, Chao said she had divested her deferred stock holding in Vulcan as well as in diversified manufacturer Ingersoll-Rand PLC on June 3.
