Katie Fallow

Katie Fallow is a senior staff attorney at the Knight First Amendment Institute, where she focuses on threats to free speech and a free press in the digital age, particularly in the area of social media.

Fallow is one of the lead lawyers in the Institute’s ground-breaking case challenging President Trump’s blocking of people from his @realDonaldTrump Twitter account on the ground that it violates the First Amendment. Fallow also successfully argued an appeal to the Fourth Circuit on behalf of a Virginia resident who was blocked by his local county chairwoman from her official Facebook page. In both cases, Fallow has helped develop an emerging body of law holding that public officials who use social media accounts for official purposes have created a public forum and may not block people from those virtual forums based on viewpoint. Fallow is also litigating the Institute’s challenge to federal regulations requiring people who apply for visas to enter the United States to register their social media handles.

Fallow regularly appears in the media to discuss the Institute’s litigation docket and comment on government regulation of public forums and digital spaces.

Before joining the Knight Institute, Fallow was a litigation partner at Jenner & Block, LLP in Washington, D.C., where she represented video game makers in a long line of challenges to government restrictions on video games, culminating in the Supreme Court’s landmark case of EMA v. Brown, holding that violent video games are protected speech. She also defended The Huffington Post and other news outlets against defamation claims and filed numerous merits and amicus briefs in the Supreme Court on free speech issues, including sexually explicit speech, offensive speech, fighting words, and libel. After leaving Jenner & Block, Fallow was deputy director of the Bureau of Consumer Protection at the Federal Trade Commission.

She graduated from the University of California at Berkeley and Harvard Law School. After law school, she clerked for Judge Robert E. Keeton of the United States District Court for the District of Massachusetts and Judge Rosemary Barkett of the United States Court of Appeals for the Eleventh Circuit.
