Former Wisconsin Congressman Mark Green is now officially the US Ambassador to Tanzania.
Green was sworn-in Thursday evening outside of a farmhouse near De Pere, surrounded by a few hundred supporters.
Green and his family will be in the east African country for about a year-and-a-half. The former Republican gubernatorial candidate was appointed to the position by President Bush.
Two decades ago, Green and his wife spent a year as volunteer teachers in Kenya. Their children have African middle names.
Green says one of his challenges will be to win over the hearts and minds of young Tanzanians.
