Congressional Quarterly informs us of a hearing scheduled for tomorrow in the U.S. House of Representatives, and lists a new witness who will be testifying:

CQ SCHEDULES Greenhouse Gas Emission ReductionHouse Energy and Commerce — Subcommittee on Energy and Air QualitySubcommittee HearingEnergy and Air Quality Subcommittee (Chairman Boucher, D-Va.) of House Energy and Commerce Committee will hold a hearing titled “Legislative Proposals to Reduce Greenhouse Gas Emissions: An Overview.”Contact: Dennis Fitzgibbons – Democratic Chief of Staff at 202-225-2927Updated Date Thursday, June 19, 9:30 a.m. Place 2123 Rayburn Bldg. Note Witnesses added. Panel Kraig R. Naasz- president and CEO, National Mining AssociationJason Grumet – executive director, National Commission on Energy Policy

Curiously, there is another individual by the same name who opines as an expert on these matters. This one:

Jason Grumet
Grumet is the Chair of the Obama campaign’s Environment and Energy Policy Committee. He has lead several non-profit and policy organizations focusing on environmental and energy issues and is frequently called to testify before Congress on climate change, global warming, bio-fuels and energy security matters.

I wonder which one will show up?
