2022–2024: The Washington Post
In March 2022, Lorenz left the Times and joined The Washington Post as a technology and online culture columnist. In April 2022, she wrote an article for the Post that publicized the identity of Chaya Raichik as the owner of the far-right Twitter account Libs of TikTok. The details were retrieved from early iterations of the account, as well as previous reporting. Raichik argued that Lorenz had doxxed her. Lorenz countered that Raichik's identity had already been publicly available. According to The Times of London, "supporters of Lorenz meanwhile pointed out that Raichik's followers were only too enthusiastic about doxing when it came to teachers being smeared as paedophiles". In a tweet, Lorenz said that her "whole family was doxed again this morning [...] trolls have now moved on to doxing and stalking any random friends I've tagged on Instagram". Lorenz later interviewed Raichik for an article in February 2024.
In May 2022, Lorenz published a report in the Post about the Joe Biden administration "pausing" the newly created Disinformation Governance Board within the Department of Homeland Security. Lorenz described a campaign of online harassment and highly critical coverage from right-wing media outlets toward the board's director, Nina Jankowicz, who resigned from the post shortly afterward. In the article, Lorenz argued that Jankowicz had been "set up to fail" by the administration, describing how Jankowicz had become the victim of attacks by online right-wing influencers and conservative media personalities, including threats of physical violence.
In June 2022, the Post published an article by Lorenz about online influencers covering the Depp v. Heard trial. The article said two YouTubers mentioned in the article were contacted for comment, but the Post later issued a correction saying only one had been contacted. The YouTuber said the request for comment only came after the article was published. In a Twitter thread reviewed by Lorenz's editors and management of the Post, Lorenz said the error was due to a miscommunication with her editor.
In December 2022, Twitter owner Elon Musk temporarily suspended Lorenz's Twitter account, tweeting that the suspension was for "prior doxxing action". Lorenz said she was suspended after asking Musk for comment on a story. The suspension followed a series of suspensions of journalists under Musk's new ownership of Twitter.
In coverage of the 2024 Democratic National Convention, Lorenz highlighted social media influencers credentialed by the DNC.
In August 2024, the Post began an internal investigation for evidence of bias after Lorenz shared an image on a private Instagram story depicting President Joe Biden with the caption "war criminal :(", a phrase criticizing United States support for Israel in the Gaza war that had previously been applied to Barack Obama. Lorenz initially denied making the post, and later said that a friend created the captioned picture, which Lorenz shared. According to NPR, four people with direct knowledge of the post confirmed its authenticity. Lorenz never published another article for The Post, which did not announce any findings of its investigation. In October 2024, she announced she was leaving the Post to start a newsletter on Substack. Lorenz told The New Yorker that her decision to leave the Post was not a direct result of the incident and that "every single President that I've ever seen in my lifetime is a war criminal".
