Don Wolfensberger at The Hill:

In the final analysis, commission-making is a significant ceding to non-elected people, at least temporarily, of Congress’s constitutional policy making and oversight responsibilities. If a problem is an immediate crisis, forming a commission is the least expeditious and least effective way to address it. In the case of the Jan. 6 attack on the Capitol, more immediate steps need to be taken by the Congress itself, and that seems to be happening, regardless of whether a commission is eventually created to address some bigger picture issues. In the meantime, both parties are exploiting the spins of commission to score political points.
