The morning news programs on ABC, CNN, Fox News, and MSNBC all allowed Donald Trump to phone in for interviews following his victories in the April 26 Republican primaries. Journalists and media critics have called out cable and broadcast news shows for allowing Trump this “shocking” “advantage,” and several programs have banned the practice.

In March, the six major broadcast and cable news networks allowed Trump to phone in for 39 of his 63 interviews. On ABC, NBC, MSNBC, and Fox News, more than half of Trump's interviews were conducted by phone.

The Associated Press has explained how television media’s unprecedented practice of allowing Trump to regularly call in gives him an advantage:

Except in news emergencies, producers usually avoid phoners because television is a visual medium -- a face-to-face discussion between a newsmaker and questioner is preferable to a picture of an anchor listening to a disembodied voice.

It's easy to see why Trump likes them. There's no travel or TV makeup involved; if he wishes to, Trump can talk to Matt Lauer without changing out of his pajamas. They often put an interviewer at a disadvantage, since it's harder to interrupt or ask follow-up questions, and impossible to tell if a subject is being coached.

Face-to-face interviews let viewers see a candidate physically react to a tough question and think on his feet, said Chris Licht, executive producer of “CBS This Morning.” Sometimes that's as important as what is being said.

Several prominent journalists and media critics have panned the media’s willingness to grant Trump phone interviews. CBS This Morning, NBC’s Meet The Press, and Fox News Sunday have all banned the practice, requiring Trump to appear in person or via satellite.
