I ran Congress’ 9/11 investigation. The intelligence committees today can’t handle Russia.

[Commentary] Since the Justice Department named a special investigator, Robert Mueller, to handle the government’s official inquiry into Russian meddling in the U.S. election, the weight of public expectation has largely fallen on his shoulders. While the two congressional panels, the Senate and House intelligence committees, continue to hold hearings and question witnesses, both are led by members of a party that is, with the exception of Charlottesville, skittish about criticizing the president. The two intelligence committees should act as if their investigations will be the final (and possibly the only) ones — because they may be.

A central role for Congress is the only real way to guarantee a full report, with conclusions and recommendations, for the American people. I oversaw a similarly complex and politically fraught inquiry as co-chairman of the joint congressional inquiry into 9/11, so I know what it takes — as a matter of resources, time, perseverance and, yes, occasional political courage — to run an investigation of this size and importance. And I know this, too: The congressional intelligence committees, as they are constituted today, are not ready for this burden.
