[6] Over the next 15 years she worked at Berman and Company and became senior vice president and communications director, leading media campaigns on a wide range of public policy issues.
[7][5] Longwell also served as managing director of the American Beverage Institute,[8][9] a trade association set up by Berman[6] that lobbies on behalf of the alcohol industry, such as by arguing that the risks of drunk driving have been exaggerated and laws that have been adopted to reduce it are ineffective or inappropriate[10] and opposing the lowering of the blood alcohol concentration limit for driving under the influence (DUI) in Utah.
[19] In 2017, Longwell was invited to participate in a session of the "Meeting of the Concerned," a quasi-secret group of Republicans who were unhappy with the direction their party had taken, where she met Bill Kristol.
After the firing of FBI Director James Comey, which triggered the Mueller investigation, Kristol and Longwell formed Republicans for the Rule of Law.
[20] The group spent more than $35 million to oppose President Trump, promoting those testimonials via social media advertising, billboard campaigns, and other tactics in key battleground states.
[28] As publisher of The Bulwark, Longwell often guest-writes columns for the website, analyzing political news of the day and pushing back against the pro-Trump movement.
[31][32] Longwell also participates in podcasts sponsored by The Bulwark with assorted co-hosts such as Jonathan V. Last, Tim Miller, and George Conway.
