Vice President Kamala Harris and former President Donald Trump are set to face off in a historic debate at the National Constitution Center in Philadelphia, marking their first encounter since Harris became the Democratic nominee. The debate is scheduled for 9 p.m. ET and will be moderated by ABC News anchors David Muir and Linsey Davis, with significant police presence expected to manage crowds and potential protests. Harris's campaign has seen a resurgence, now nearly tied with Trump in swing state polls following President Biden's withdrawal from the race. The event is anticipated to feature heightened tensions, as both candidates are mobilizing their campaigns heavily in the city, including numerous watch parties and advertising efforts. Philadelphia last hosted a presidential debate in 1976, adding to the significance of this event during an election cycle marked by intense political dynamics. Traffic adjustments and barricades are in place around the venue to ensure safety and order during the debate.
