Does the word “bias” mean anything to you for someone who’s job involves editing content that gets aired on GMA?
I worked in television for 25 years. An Avid Editor (Avid is a brand of computer software for video editing) does not make editorial decisions. They put together what the producers and reporters tell him/her to put together. They're like the "Sandwich Artists" at Subway. They make the sandwiches, but only under the direction of the customers. It doesn't really matter if they're biased against Black Olives, if the customer asks for them, they'll put them in the sandwich.
With all of the Leftists at ABC who are on-air talent, executive producers, associate producers, directors, and writers being rabidly anti-Trump, a lowly line editor doesn't make any difference. They'll take the footage they're given and put together the package they're told to put together.
