Donald Trump has threatened to withdraw from the upcoming presidential debate with Kamala Harris scheduled for September 10, claiming the ABC network is biased and suggesting it may favor Harris. Trump's campaign insists they had agreed to a muted microphone format, similar to a previous debate, while Harris' team advocates for an open microphone policy to allow real-time responses. Trump's remarks on social media questioned the network's fairness and included criticism of their panelists, while he also expressed dissatisfaction with being muted in the last debate. The Harris campaign argues that they are prepared for Trump's interruptions and wants the debate format to reflect this capability. Meanwhile, Trump's comments indicate a lack of preparation for the debate, stating he feels he has been preparing for it his entire life. The situation has led to a public spat between the two campaigns, with both sides trading barbs over debate rules and network integrity.
