ABC News' Muir mocked for making his firefighter coat more form-fitting for wildfire report

Social media users piled on ABC News anchor David Muir over his more form-fitted appearance in a recent news report about the Southern California wildfires.

During an "ABC World News Tonight" report on Wednesday from the scene of the devastating fires, anchor Muir could be seen wearing a yellow fireproof jacket with the ABC News logo emblazoned on it. At one point during his reporting, Muir turned to his left and revealed what appeared to be clothespins keeping the jacket tight around his body.
