Reportedly, the two of them do get around. According to Breitbart:
For example, Cochran and Webber traveled eight times to France, five times to Italy, four times to Israel, and twice to Japan.The full list of countries they traveled to includes: Italy, France, Brussels, Ireland, the United Kingdom, Belgium, Hungary, Russia, Norway, Germany, Spain, Portugal, Greece, Malta, Austria, and Czech Republic in Europe; Colombia, Brazil, Paraguay, Uruguay, Argentina, and Chile in South America; Guatemala, and Mexico in North and Central America; Japan, China, Kyrgyzstan, Malaysia, Vietnam, Hong Kong, the Republic of the Philippines, and South Korea in Asia; Turkey, Jordan, Israel, Azerbaijan, Oman, and United Arab Emirates in the Middle East, to Morocco; and Egypt, Cape Verde, and South Africa in Africa.
Other documents show that in 2005 and 2007, the Wine Institute, a trade association that represents the California wine industry, paid for Cochran's and Webber's travel to Sonoma, California for what a disclosure form described as “a fact-finding program on issues of importance to the wine industry.” No other aides attended the trip.
