Margaret Brennan: I spoke with Lindsey Graham a day before he died

Lindsey Graham, a staunch advocate for Ukraine, died shortly after his tenth visit to the warzone, marking a significant moment for his efforts in securing strong sanctions against Russia. This comes amid ongoing geopolitical tensions and as his support was crucial in the U.S. Senate. Graham's legacy in championing Ukraine's cause and pushing for robust sanctions underscores the importance of his work in the context of international relations and the global fight against aggression. His death highlights the personal risks and dedication some politicians undertake in support of critical foreign policy initiatives.
