A statement from Conrad's office said the "primary purpose of the delegation's visit to Madrid is to better understand the economic challenges facing Spain and other members of the Euro area."

Alan Solomont, the U.S. ambassador to Spain, said the visit "is an example of how the U.S.-Spain relationship is a top priority for the political leaders in the United States. The United States is committed to standing with Europeans and the people of Spain as they put in place a comprehensive solution to the current economic crisis in Europe."
