Tim Walz and JD Vance argued in their vice presidential debate that their running mates would reduce tensions in the Middle East and address natural disasters in the US. Walz criticized Donald Trump's leadership and emphasized the need for steady leadership in unstable times. Vance defended Trump's presence on the international stage as a deterrent. Both candidates expressed unity in addressing the devastation caused by Hurricane Helene. The debate could have a significant impact on the close contest between Vice President Kamala Harris and former President Donald Trump.
