(CNN) Before her death, Jo Cox had become increasingly worried that politics was getting extreme, that things were turning "too tribal and unthinking," said Brendan Cox, her widower. "She was very worried that the language was coarsening and people were driven to take more extreme positions," he told the BBC. Cox was a rising star of the Labour party and a vocal advocate of Britain remaining in the European Union. She championed for the rights of immigrants and was particularly vocal about Syrian child refugees. Last week, the 41-year-old politician was fatally shot and stabbed in Birstall in northern England.Jo Cox was killed because of her views, says widowerPolitician supported Britain staying in the EU in contentious referendum
