Who knew that “Trump” was a four-letter word?

Yet in a story aired Wednesday about a man who saved a baby from a hot car, CNN’s Headline News (HLN) chose to censor the Good Samaritan's “Trump for President 2016” T-shirt on air.

Steven Eckel, a 53-year-old retired police officer, smashed through the windshield of a car in New Jersey earlier this week when he spotted a baby trapped inside in 90-degree heat after being left there by her mother.

When interviewed about the incident by HLN Wednesday, Eckel chose to wear a “Trump for President 2016” shirt as he told his story about how he rescued the baby. His bright blue shirt could be seen on the first airing on HLN.

However, as flagged by The Daily Caller, when the interview was re-aired later in the day, HLN chose to blur out the logo, as one might blur out an obscenity.

HLN later said this was a mistake: "We blurred the logo and shouldn’t have; it was done in error,” an HLN spokesperson told The Hill.

This comes after HLN last week canceled Dr. Drew Pinksy’s “Dr. Drew on Call,” just days after he questioned Hillary Clinton’s health and medical care. CNN did not give a specific reason for the cancellation.
