U.S. Sen. Amy Klobuchar visited Senegal, Ethiopia and Tanzania to discuss food security and Somali refugees during an 11-day fact-finding trip.

Klobuchar's office said she took the trip to review "the significant agriculture and aid investments we have in Africa and make sure they are effective and making progress so that countries are able to start building their own economies."

While in Africa, Klobuchar also met with officials from the United Nations High Commission on Refugees and Ethopia's Administration for Refugees to discuss Somali refugees in Ethiopia and how to strengthen the security situation inside Somalia.

Sen. Debbie Stabenow of Michigan, Sen. Maria Cantwell of Washington, Heidi Heitkamp of North Dakota and Mazie Hirono of Hawaii were also part of the delegation, according to the Tanzania Daily News.

The group – which returned to the United States this week -- also visited the Serengeti National Park and Rome, headquarters of the U.N. Food and Agriculture Organization.
