The congressmen who visited the school Mr Wicker, Mike McIntyre, Robert Aderholt and Joe Wilson are members of the US Congress Friends of Scotland caucus. Last week, they paid their first official visit to Scotland since the caucus, which has 40 members, was formed in 2006.
"We want to promote friendship and understanding between two very, very good allies," said Mr Wicker, who represents Mississippi's First Congressional District. "This visit is to sample a number of aspects of Scottish culture."
