Congresss subpoena power is not what it used to be
Congresss power to enforce subpoenas by exercising its contempt power is now really toothless, said Randall Eliason, a former federal prosecutor who teaches at George Washington University Law School.
The reason, in part, is that Congress relies on the very Justice Department it is pursuing to prosecute the contempt citation.
And the Justice Department has, in the past, simply declined to do so.
That leaves Congress only one route: a possibly interminable civil litigation.

The difference is between "Congress finds contempt" and "Court finds contempt." The first one is a badge of honor.
