Sen. Elizabeth Warren endorsed Vice President Kamala Harris at the Democratic National Convention, claiming Harris would lower grocery prices and handle economic issues better than former President Donald Trump. Minnesota Gov. Tim Walz accepted the Democratic vice-presidential nomination, emphasizing his Midwestern roots and progressive achievements, including education investments and paid family leave. Walz, selected to appeal to working-class voters, also faced scrutiny over misleading claims about his teaching awards and military service. The convention aimed to introduce Walz to the national stage and bolster Harris's campaign as she leads the Democratic ticket.
