The presidential campaigns of Vice President Kamala Harris and former President Donald J. Trump are engaged in a very public fight over the rules of their first debate, scheduled for Sept. 10. The wrangling — including Mr. Trump’s complaints about fairness — has elicited a strong reaction across the spectrum of political media.

In recent days, Mr. Trump has repeatedly attacked the credibility of ABC, the network hosting the debate, and has wavered in his commitment to debating Ms. Harris. At the same time, Ms. Harris’s campaign has lobbied the network to return to leaving the microphones unmuted throughout.

Conservative commentators on TV and online have denounced the request from Ms. Harris’s campaign as flip-flopping, maintaining that Ms. Harris is “scared” of debating Mr. Trump and suggesting that she is seeking a convenient excuse to back out. They have also parroted Mr. Trump’s complaints about ABC, which they have claimed without evidence is biased in favor of Ms. Harris.

Liberal commentators have claimed that Mr. Trump, not Ms. Harris, is inventing excuses in order to exit the debate, and have referred to him as “weak.”

Here’s how a selection of outlets has covered the debate over the debate:

Before the June debate, President Biden’s team pushed to mute the microphone of the candidate who wasn’t speaking so that Mr. Trump would not interrupt Mr. Biden. But this week, Ms. Harris’s team asked that the network keep the microphones live throughout the debate. A spokesman for Ms. Harris’s campaign suggested that Mr. Trump’s team had objected to the request out of concern he could not “handle himself” with a live microphone.
