Don Wolfensberger at The Hill:
Restoring trust in Congress will take a concerted effort over time to move overly zealous executive officials back into their proper constitutional boxes. To restore trust in Congress requires that Congress first regain trust in itself. That requires the first branch showing respect for its power and the intent to exercise it.
That will mean restoring the primacy of committees over legislating and oversight, and reducing party leadership dominance proportionately. It also means confining the executive branch to working within the statutory parameters Congress sets. It is a tall order but achievable if Congress can rally self and the people behind it.
