In recent weeks, some of America’s most powerful law firms have faced a defining choice: do a deal with the White House, or prepare to fight severe restrictions President Donald Trump has placed on firms and lawyers he opposes politically.

Facing potentially ruinous sanctions from Trump because of past or current work he opposes, two high-profile firms cut deals with the White House, fueling fears in some portions of the industry that Big Law would cave to Trump’s tactics, upending how large firms have done business for decades in Washington.

But Friday morning, Jenner & Block, and WilmerHale, two large firms built around litigation and Washington contacts, sued the administration to challenge Trump executive orders targeting them and their clients. The firms accused the government of using unconstitutional executive orders to punish or chill speech it doesn’t like.

The development was an encouraging shift for many lawyers agitating for the industry to stand up cohesively for the rule of law. The staying power of the pushback on Trump remains uncertain. Even if Trump’s orders are found unconstitutional, some lawyers fear damage to their business is already done because new clients may avoid firms that Trump has a grudge against.

While some smaller firms have spoken out against the president’s orders, and even among conservatives the orders have raised constitutional concerns, many big firms have stayed silent hoping to avoid Trump’s wrath.
