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.

President Donald Trump sought to cut off Perkins Coie, a Democratic law firm accused of wrongdoing in the Russia investigation.

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