The upcoming presidential debate faces uncertainty as the Trump and Harris campaigns clash over microphone rules."I don't know. It doesn't matter to me, I'd rather have it probably on, but the agreement was that it would be the same as it was last time. In that case, it was muted," former President Donald Trump said.The debate, initially agreed upon by the Trump and Biden campaigns for Sept. 10, now faces potential changes due to the shift in the Democratic ticket.The Harris campaign is pushing for microphones to remain on during the debate, a departure from Biden's previous strategy.The Trump campaign remains non-committal about the microphone rules, while the Harris campaign believes keeping the mics on could expose Trump's behavior to independent voters."I think Harris thinks that by having the mics on is going to have Donald Trump run away at the mouth and, you know, really engage in the type of bullying behavior that has really turned off a lot of those independent voters," political analyst Todd Belt said.Harris is set to kick off a bus tour in Georgia on Wednesday followed by a campaign event in Savannah, Georgia. Meanwhile, Trump plans to spend time in Wisconsin and Pennsylvania later this week.
