(CNN) -- George Stanley McGovern, a staunch liberal who served South Dakota in the U.S. Senate and House for more than two decades and who ran unsuccessfully as the Democratic Party nominee for president in 1972, died Sunday at the age of 90, his family said.
"Our wonderful father, George McGovern, passed away peacefully at the Dougherty Hospice House in Sioux Falls, SD, surrounded by our family and life-long friends," his family said in a statement.
"We are blessed to know that our father lived a long, successful and productive life advocating for the hungry, being a progressive voice for millions and fighting for peace. He continued giving speeches, writing and advising all the way up to and past his 90th birthday, which he celebrated this summer."
Services will be scheduled in Sioux Falls, the family said.
