Five years ago I joined a client as she testified to the House Government Reform Committee on which Rep. Cummings served. Though the client was blowing the whistle about misconduct that occurred at an agency headed by a Democratic appointee, Rep. Cummings did not hesitate to say on the record that it was among the worst things he had heard in his 17 years in Congress. I’d wish for a hundred more Rep. Cummings: unafraid to show their humanity, unafraid to criticize even their own party when it goes astray, unafraid to maintain friendships across party lines. The nation has lost a hero.
