House Subpoena Press Conference in Washington D.C.

A press conference is held outside the U.S. Capitol by politicians, legal experts and leaders of environmental groups to raise concerns about subpoenas issued by Rep. Lamar Smith (R-Texas), chairman of the House Committee on Science, Space and Technology to non-governmental organizations and attorneys general of two states. Smith is holding a hearing on his authority to issue and enforce the subpoenas seeking emails between non-governmental organizations and attorney generals about Exxon Mobil's decades long campaign to mislead the public about climate change. Exxon's scientists knew about the connection between the use of fossil fuels and climate change while the company pursued policies designed to cast suspicion on the problem.
