It’ll likely take a subpoena to reveal the identity of Devin Nunes’ Cow. Even so, the Republican congressman’s defamation lawsuit against Twitter involving the parody social media account may have more meat to it than one might expect.

Libby Locke, a partner at Clare Locke, a Kirkland & Ellis spinoff in Alexandria, Virginia, says the case brought by the California politician—widely lampooned in the press and on social media as silly and self-destructive—involves some critical issues pertaining to social media, parody and immunity that have yet to be determined. Last week, Locke and her husband Tom Clare led a team in winning a $26 million defamation verdict in North Carolina against Puma Biotechnology and its CEO.
