Henry Waxman: “This is the dirtiest source of oil from these tar sands, and that is what I meant to say.”

It is not for the President to say or to obstruct congressional deliberations and investigations or other legitimate functions.

I think of how Henry Waxman showed America the true face of the tobacco industry, exposing decades of deceit.

The House's need for all the facts surrounding suspected Presidential offences cannot of course be circumscribed by an executive determination of what is relevant.

I hope this committee will initiate a detailed investigation examining this network of front groups and trade associations, determine who funds them and expose how they coordinate with industry.
