Live on stage at the CNN-POLITICO Grill in Chicago, host Anne McElvoy talks to U.S. Senator Tammy Duckworth.

The Illinois senator — a decorated war veteran — has fiercely defended the military record of Tim Walz, the running mate of Democratic presidential candidate Kamala Harris, against Republican criticism that he exaggerated his service. Here at the DNC, Duckworth discusses Harris' economic plans and talks passionately about her use of IVF as a row deepens with Republicans over fertility treatment. She goes on to say that Harris will "kick [Trump's] butt" when they meet in their televised debate next month.
