The Fox opinion hosts have been two of Trump's biggest backers for a long time, but like many critics concerned about the Fox News-White House dynamic, several of the network's employees say Hannity and Pirro's shilling puts them in an extremely hard position.
Then the Fox News host approached the podium and wagged his finger at the media, which included reporters with Fox News.
This came after Hannity insisted that he would interview the president back stage and hold a live show from the venue, but wouldn't actually get on stage to campaign on the president's behalf.
Hope Hicks, chief communications officer for Fox - the soon-to-be parent company of Fox News - did not respond to a Tuesday morning email asking whether Rupert or Lachlan Murodch, the father and son who control Fox News, had any comment on or approved of Hannity's behavior.
"While we often hear that all politics is local, there's just no getting away from the fact that Trump's policies are on the ballot", said host Laura Ingraham on Fox News' "The Ingraham Angle" during her opening monologue, in which she focused on protecting and preserving America's and Americans' future.
Hannity, cable news' most popular personality, told the crowd, "By the way, all those people in the back are fake news".
The Fox News host also had bodyguards with him as he greeted guests at the event amd paused for photos.
"We were all told that Hannity was going to interview the president, but no one that I spoke with expected what happened last night", added a third senior Fox News employee.
He warned earlier on the telephone town hall to get out and vote because "the press is very much considering it a referendum on me and us as a movement".
As emergency workers made their way to the woman, Trump said: "Take your time". Fox has not addressed the question publicly.
Trump called Hannity to the stage after praising Fox, saying, "they're very special, they've done an incredible job for us".
Limbaugh said it was "a great honor" to be a guest at one of Trump's electrifying rallies, noting that they were the "envy" of professional Washington, DC. "Anyone doing business with Fox News should worry about the network's inability to enforce even the most bare minimum standards". Then, when Trump called him up, Hannity quickly went from "covering the final rally for [his] show" to becoming part of the show.
But at the IN rally, the president relished IN making Democrats go nuts and said he's not yet ready to tone it down.
A network spokesperson pleaded against Hannity taking the stage with the president in a statement on Tuesday.
