Last month, as 100 Harvard law students gathered for a reception hosted by Paul, Weiss, Rifkind, Wharton & Garrison LLP, the festivities were interrupted by a small group of students waving a banner that read #DropExxon and singing Pete Seeger's "Which Side Are You On?" 

The event, which caught some media interest, signaled a mini-movement. The following month, during a Paul Weiss event for Yale students, another group of protestors unveiled the same banner and chanted similar admonitions. Most recently, a third protest by NYU law students targeted Paul Weiss in New York 

These students are exercised over Paul Weiss' representation of ExxonMobil in climate change matters, including a victory in a case brought by the New York Attorney General alleging the company misled investors about the costs of climate change regulation. Even the Daily News, New York's liberal tabloid, branded the case "dubious." Elsewhere, cities are after ExxonMobil and other companies to pay for the impacts of climate change.
