The President’s recent attacks on lawyers and law firms for daring to have represented the President’s personal enemies or causes that he and his supporters dislike are dangerous threats to the rule of law and our democracy.

We are proud to represent clients who are suing the government for unlawfully disclosing the highly sensitive, personal information of tens of millions of Americans, and we stand unequivocally with other principled lawyers who are living up to their obligations to defend the rule of law.
