(NewsNation) — Vice President Kamala Harris and Minnesota Gov. Tim Walz will be making their first post-convention campaign appearance this week even as Harris’ team argues with former President Donald Trump over debate rules.

Several events and rallies in key swing state Georgia will happen ahead of a two-day bus tour. As Harris and Walz attempt to ride the momentum from the Democratic National Convention, there are now questions about whether a planned debate on Sep. 10 will happen.

Harris and Trump have been going back and forth about the upcoming debate set to air on ABC. Trump has indicated he doesn’t want to participate in the debate anymore while Harris’ team has been working on crafting a strategy for the previously agreed upon debate.

Trump has been questioning ABC News as a platform and also objecting to proposed rule changes.

“I think ABC should be shut out. I’d much rather do it on NBC. I’d much rather do it on CBS, frankly, I think CBS is very unfair but the best of the group. Certainly, I’d do it on Fox, I’d even do it on CNN,” Trump said. “They also want to change the rules. The deal was we keep the same rules. Now, all of them said they want to make a change in the rules because she can’t answer questions.”

The main rule in question is regarding live mics. Politico has reported an impasse over whether microphones will be muted. The Harris campaign responded with a statement saying in part, “Our understanding is that Trump’s handlers prefer the muted microphone because they don’t think their candidate can act presidential for 90 minutes on his own.”

The communications director for the Harris-Walz campaign said on Monday that Harris is prepared to lay out her vision for the economy, women’s rights and other key policy issues. She is also reported to be preparing for what her campaign expects to be a flood of falsehoods from Trump.

Meanwhile, with 71 days to go until Nov. 5, the Harris campaign’s bus tour will end with a rally in Savannah, with more details coming soon.

The Harris-Walz also set a record for donations, which has now raised $540 million. That’s the most for any presidential candidate in the time span from when she launched her campaign.

The best fundraising day since the campaign’s launch is said to be the hour following the vice president’s convention speech, with $82 million raised in just one week.

The campaign is also said to be casting a wide net and recruiting House Democrats to stump for the ticket, with Democratic lawmakers and aides describing the surrogate campaign as “night and day” when compared to operations for President Joe Biden.
