Paul Weiss, the New York law firm that this week struck a deal to escape President Trump’s wrath, is one of the nation’s largest, with more than 1,000 lawyers representing some of the world’s wealthiest and most profitable companies.

The firm, formally called Paul, Weiss, Rifkind, Wharton & Garrison, has offices around the world. Its work involves mergers and acquisitions, private equity, white-collar and regulatory defense and litigation. Clients have included corporations like ExxonMobil, Citigroup, Imagine Entertainment and Lucasfilm.

Paul Weiss’s revenue was more than $2.6 billion last year, according to Law360. The firm also has a large pro bono practice of public service work, some of which will now be performed for causes championed by President Trump, according to the deal.

The president had issued an executive order, part of a broader campaign against law firms, which would have suspended Paul Weiss’s security clearances and barred its lawyers from federal buildings. To persuade the president to lift the order, the firm agreed to do $40 million worth of pro bono work on causes, such as working with veterans and fighting antisemitism, over the course of Mr. Trump’s term.

But the deal with Mr. Trump has led some critics to charge that Paul Weiss betrayed its principles by giving in to the president rather than fighting him in court.

The firm is known for giving a home to prominent Democrats, like Theodore C. Sorensen, who was an adviser to President John F. Kennedy.
