Former President Donald Trump has confirmed that he will participate in a presidential debate with Vice President Kamala Harris on September 10, hosted by ABC News in Philadelphia. The agreement follows contentious negotiations over debate rules, particularly regarding whether microphones should be muted when not in use by the speaking candidate. Trump announced the debate rules will mirror those of his previous CNN debate with President Biden, which included muted mics, no notes, and no live audience. Harris' campaign had initially pushed for live microphones throughout the debate, but Trump's team resisted, leading to the final agreement. The debate will be moderated by ABC's David Muir and Linsey Davis. Both campaigns are actively preparing, with Harris engaging in mock debates and Trump maintaining his usual approach to avoid formal preparation.
