I do agree that, in general, some of of the so-called "town halls" on various networks have planted people from a political party asking biased questions and/or irrelevant/ignorant questions.
There was an Oct. 15 event in Georgia billed as a women's town hall asking Trump questions.
It aired on Fox but it was edited. According to CNN:

“I want to thank you for coming to a room full of women the current administration would consider domestic terrorists,” a woman named Alicia said to laughter from the audience before a question about foreign policy.
But a portion of Alicia’s question was edited by Fox News to remove her admission that she was voting for Trump.
“I proudly cast my vote for you today. I hope they count it,” she added, according to an audio recording from a CNN reporter in attendance.
While it’s common for a pre-taped event or interview to be edited for time, Alicia’s short remark came in the middle of her question, which remained intact on the broadcast.
During another moment missing from Fox’s broadcast, Trump asked the crowd who they were voting for, leading to a chant of “Trump, Trump” breaking out by the attendees.
Fox News did not respond to CNN questions about the missing remarks.
Yeah I agree there definitely needs to be more fact-checking on both interviews and on town halls.
