Michael De Adder/Twitter Michael de Adder shared the cartoon depicting U.S. President Donald Trump and the border crisis on his social accounts.

The Canadian cartoonist who drew a viral depiction of U.S. President Donald Trump and the border crisis is defending his own credibility after his contract was terminated by a newspaper publisher. “It sounds corny, but I have a personal code of conduct. It’s kept me employed for 20 years in a business that’s been dying for 10,” Michael de Adder wrote on Twitter on Monday.

He posted a cartoon last week which shows Trump standing by a golf cart, asking “Do you mind if I play through?” while standing above two bodies. The image recalls the drowning of Óscar Alberto Martínez Ramírez and his 23-month-old daughter, Valeria, in the Rio Grande River as they tried to cross the Mexico-U.S. border. That same week, his freelance contract with Brunswick News and their four newspapers in New Brunswick was terminated. The cartoon was not published in the papers but was shared widely on social media.

De Adder told HuffPost Canada on Sunday that speculation his contract end was linked to the viral Trump cartoon was “hitting it on the nose.” He expanded on those thoughts on Twitter Monday. In his 20-year career, he said he was careful not to burn bridges with any employer, regardless of disagreements. He noted the 17 years he has worked with Brunswick News, which is privately owned by the Irvings, one of Canada’s richest families. But De Adder said he felt he had to defend himself “reluctantly” because he felt “cornered.” He added that the recent death of an uncle put the job loss in perspective.

I could write a thesis on my experience at the newspaper that would be captivating. But do you know what? I'm not going to. They gave 17 years of employment and gave me a job when the Daily News folded. And what would that say about me? — Michael de Adder (@deAdder) July 1, 2019

I do this relunctanly and only because I'm cornered. And I don't know how it happened, but I feel my credibilty is on the line. And all I did was lose my job. — Michael de Adder (@deAdder) July 1, 2019

De Adder said that every cartoon featuring Trump that he submitted for consideration was rejected “to the point where I didn’t submit any Donald Trump cartoons for fear that I might be fired.” In denying accusations that de Adder’s contract was killed over the viral Trump cartoon, Brunswick News said, “This is a false narrative which has emerged carelessly and recklessly on social media.” In a statement on Sunday, the company stated that negotiations had been “ongoing for weeks” to bring back another cartoonist to its pages.

Brunswick News controls nearly all of the newspapers in New Brunswick, including three dailies, and several French and English weekly publications. It has been accused of shying away from publishing stories critical of the Irving Group of Companies (its parent owner) and its subsidiaries. The companies — which include oil and gas, shipping and transportation — are worth an estimated $10 billion. On Monday, De Adder said the Trump issue is a “distraction from the big picture,” pointing out that much of his work actually focuses on Canadian politics, including N.B. Premier Blaine Higgs.

The Premier of New Brunswick Blaine Higgs is a former Irving Oil executive and any cartoon I drew that was slightly critical of him was systematically axed. You want to know why I was let go? I wanted to do my job as an editorial cartoonist, and they wanted me to do their job. — Michael de Adder (@deAdder) July 1, 2019

With this said, I had been giving the NB newspapers what they want for several months. Trump wasn't on my radar. I work for canadian newspapers so there's no need to cover Trump 24/7. And Canadian politics is quite interesting right now. — Michael de Adder (@deAdder) July 1, 2019

But in the past 2 weeks I drew 3 Trump cartoons. 2 went viral and the third went supernova and a day later I was let go. And not only let go, the cartoons they already had in the can were not used. Overnight it was like I never worked for the paper. Make your own conclusions. — Michael de Adder (@deAdder) July 1, 2019

UPDATE - July 2, 2019: Brunswick News released a follow-up statement about “false information spread widely across social media.” In referencing “an era of fake news,” the company reaffirmed that de Adder’s contract cancellation was not linked to the viral Trump cartoon. However, Brunswick News did not respond specifically to HuffPost’s question about de Adder’s claim that any critical Higgs cartoon he drew was “systematically axed.” “BNI’s opinion pages remain a place of balanced debate, with a focus on local issues affecting New Brunswickers,” said the statement.
