De Adder presented Trump and asked the two dead migrants: "Does it bother you if I play through?"
"The ups and downs of drawing – today, I was simply fired from all the newspapers in New Brunswick," tweeted De Adder. Later, he made it clear that he was technically under contract to work for Brunswick News Inc. and was not an employee who could be fired.
"This is a false narration that has appeared carelessly and ruthlessly on social media," the publisher wrote. It was said that de Adder had never offered the company the Trump cartoon and had already decided to "bring back" another cartoonist who was popular with readers. "[N] Ego negotiations were going on for weeks," it said.
He did not respond to a request for further comments from CNN Business.
Wes Tyrell, president of the Association of Canadian Cartoonists, a professional group of artists, claimed that the Braunschweiger newspapers avoided Trump as the subject of their cartoons – and de Adder "did this with regularity in recent years, like any cartoonist."
