President Donald Trump apparently wasn't the only politician Twitter C.E.O. Jack Dorsey spoke with on Tuesday. Following the C.E.O.'s meeting with Trump to discuss Twitter—and the president's follower count—the Washington Post reported Thursday Dorsey had also reached out to the other side of the aisle that day, calling Democratic Rep. Ilhan Omar after a Trump tweet sparked widespread death threats against the freshman congresswoman. During the conversation, Dorsey reportedly defended leaving the tweet up—a decision that reflects Twitter's current conundrum in how to deal with far-right speech.

Per the Post, Dorsey reportedly claimed Trump's tweet, which juxtaposes comments made by Omar with footage of the September 11 attacks, does not violate Twitter's rules. He also pointed to the fact the video had spread beyond Twitter to defend not deleting the tweet, though he did tell Omar that Twitter “need[s] to do a better job generally in removing hate and harassment from the site.” Twitter confirmed the call in a statement, saying Dorsey “emphasized that death threats, incitement to violence, and hateful conduct are not allowed on Twitter.” “We’ve significantly invested in technology to proactively surface this type of content and will continue to focus on reducing the burden on the individual being targeted,” the company added. Twitter has previously been reticent to censor Trump's tweets in any way, claiming that blocking or removing tweets by an elected world leader “would hide important information people should be able to see and debate.”

Dorsey's defense of leaving up Trump's damaging tweet—on the same day as his “constructive meeting” with Trump himself—comes as Twitter apparently reckons with how to assuage the president and the Republican Party while listening to users' pleas for it to “ban the Nazis.” Vice's Motherboard reported Thursday that, according to alleged statements made by one Twitter employee, Republican lawmakers are apparently keeping the site from banning white supremacists—and not through their lobbying. Though the company was able to quash ISIS supporters on Twitter by using an algorithm, using similar tactics to block white supremacists would reportedly inadvertently target Republican politicians as well, per Motherboard's report. “When we try to talk about the alt-right or white nationalism, we get into dangerous territory, where we’re talking about Steve King or maybe even some of Trump’s tweets,” Amarnath Amarasingam, an extremism researcher at the Institute for Strategic Dialogue, told Motherboard. “It becomes hard for social media companies to say all of this ‘this content should be removed.’”

Twitter has strongly denied the Motherboard report, saying in a statement that it has “absolutely no basis in fact” and disputing the “characterization of the exchange” at the meeting in which the comments allegedly took place. “There are no simple algorithms that find all abusive content on the Internet and we certainly wouldn't avoid turning them on for political reasons,” the statement said. The company previously said in a statement to The Hive, in response to Dorsey's apparent refusal to kick white supremacists off of Twitter, that Twitter “[has] policies that explicitly state that account holders cannot harass, intimidate, or threaten someone on the basis of them belonging to a protected category. This includes race, religion, and sexual orientation.”

Though it denies the comments, Twitter clearly struggles with how to handle the insurgence of white supremacy that's taken place on its platform, particularly in the age of Trump. Dorsey has typically been evasive when questioned about banning white supremacists, only saying, “we’d certainly talk about it,” when asked point-blank if Trump asking his followers to murder journalists would warrant a ban. There's also the widespread Republican conspiracy theory that the site discriminates against conservative voices to contend with, which Dorsey has helped stoke by suggesting that Twitter employees' biases are “more left-leaning.”

Yet Dorsey's acknowledgement to Omar that the company has to do better about hate speech potentially could have some promise. In a March conversation with the Washington Post, Vijaya Gadde, Twitter’s head of legal, policy, and trust and safety, suggested that the company is exploring ways to annotate tweets in the public interest that violate Twitter's rules, a small step that would at least show some attempt to mitigate the president's more unhinged Twitter rants. “One of the things we’re working really closely on with our product and engineering folks is, ‘How can we label that?’” Gadde said. “When we leave that content on the platform, there’s no context around that, and it just lives on Twitter and people can see it, and they just assume that is the type of content or behavior that’s allowed by our rules.”
