AP prohibits employees from openly expressing their opinions on political matters and other public issues for fear that could damage the news organisation's reputation for objectivity and jeopardise its many reporters around the world.
"We have this policy so the comments of one person cannot create dangerous conditions for our journalists covering the story," Easton said. "Every AP journalist is responsible for safeguarding our ability to report on this conflict, or any other, with fairness and credibility, and cannot take sides in public forums."
In an interview, Wilder said she had received social media training from the AP and had taken it seriously. She said she had even taken down a reference to supporting Black Lives Matter from her Twitter profile.
"Because I have an opinion about an issue that is deeply political and personal doesn't mean that I am incapable of fact-based, contextual and fair journalism," she said.
She also said: "There's no question that this was all precipitated by an onslaught of harassment against me."
Two days before her firing, a Twitter post from Stanford Republicans had criticised Wilder, who is Jewish, as an "anti-Israel agitator" while on campus. They posted a 2019 article she had written in the college newspaper referring to conservative media figure Ben Shapiro as "a little turd". Shapiro has been fiercely critical of the Palestinians.
An article in the Washington Free Beacon was headlined, "AP Hires Anti-Israel Activist as News Associate. AP's Objectivity in Question Amid Revelations it Shared Office Space with Hamas." It was picked up in other forums, including the Fox News website.
Over the past few days, AP itself has been criticised by some conservative figures following the Israel airstrike last Saturday that destroyed the building that housed the news agency's offices in Gaza. The AP has said it had no knowledge Hamas operated out of the building, as Israel claimed.
After the bombing, the AP sent a memo to its staff members reminding them of its policy against expressing opinions on contentious public issues.
Janine Zacharia, Wilder's journalism professor at Stanford and a former Jerusalem bureau chief for The Washington Post, said she could not understand why the AP didn't just discuss concerns about the tweets with Wilder instead of firing her.
Zacharia said she believes Wilder's activism in college was the real issue and worries about the message the AP is sending. Many one-time activists put their passion into journalism, as Wilder did as an intern at The Arizona Republic, she said.
"What happens if you were a college activist and then decide that you want to become a journalist?" she said. "Does this mean that you can't?"
Social media and the generation that has grown up with it have posed challenges at news organisations as they try to uphold standards of objectivity. The AP maintains doing so is important for an organisation whose calling card is fairness.
"It's important to recognise that for an organisation like the AP, there are colleagues all over the world covering every possible topic," said Kathleen Carroll, the organisation's former executive editor and now chairwoman of the Committee to Protect Journalists.
"That's why journalists covered by the social media policy need to be careful that their posts don't jeopardise the ability of their colleagues to work freely," Carroll said. "What may be personal expression to one person is right at the heart of a story to a colleague somewhere else."
The AP stressed that the firing was based on what Wilder had done while employed at the news organisation, and had no further comment.
As for the news organisation's use of terminology, the AP Stylebook urges against references to "Palestine" because it is not a fully independent, unified state. The AP has made references to Israeli occupation and said that Gaza - and Israel — have been under siege during the latest fighting.
