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 D.C. federal judge said she will temporarily halt a Trump executive order targeting the law firm Perkins Coie, which represented Hillary Clinton.

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