At least a couple large law firms are in the process of gathering signatures for an amicus brief in support of Perkins Coie’s lawsuit against the Trump administration, sources say.

A judge imposed a temporary restraining order against the Trump administration, barring it from enforcing parts of an executive order penalizing a law firm.

A U.S. judge blocked provisions of President Donald Trump's order targeting attorneys at Perkins Coie on Wednesday, saying the legal profession was "watching in horror" at what the law firm was experiencing.
