Joao Vale de Almeida, Ambassador of the European Union to the United States, visited Pierre Tuesday morning. It was one of a handful of stops Almeida is making in the Midwest. As the most senior official under the authority of the High Representative/Vice-President Baroness Ashton, he helped formulate and execute the EU's foreign policy and played a key role in preparing for the new European External Action Service introduced by the Treaty of Lisbon. Ambassador Almeida also acted as the EU "Sherpa" for G8 and G20 Summits.
