There’s no witness list available, yet, but Congress will hold a hearing on grassroots lobbying this Thursday.

Chairman Edward J. Markey (D-Mass.) of the Select Committee on Energy Independence and Global Warming announced today that he will be holding an investigative hearing into the fraudulent letters sent to Congress on clean energy and climate legislation. The Select Committee has now discovered more than a dozen fraudulent letters were sent to several members of Congress as part of an “Astroturf” campaign run by the firm, Bonner & Associates, and contracted by the American Coalition for Clean Coal Electricity. This campaign was designed to influence members of Congress on the House-passed Waxman-Markey climate and energy bill.
