With both houses of
Congress under a Republican majority, investigating the malfeasance of
the oil industry has not been a priority. Instead, Republicans have held
hearings investigating the officials who are investigating the oil
industry.
However, with the House moving to Democratic control, Congressional oversight will become a renewed priority. That primarily involves overseeing the work of the Executive Branch, but also includes corporate behavior of national interest.
The “ExxonKnew” controversy is the evidence that Exxon and other oil majors knew for decades that their products cause dangerous global warming but decided to run a disinformation and political interference campaign to avoid regulation of their pollution.
A leading Congressman in calling for investigation is Rep. Ted Lieu (D-Calif.) who repeatedly called for Congressional investigations in 2016. However, he is not currently on the committees with jurisdiction (that could change in the new year).
Another is Rep. Jared Huffman (D-Calif.), a former attorney for NRDC, who sits on the Natural Resources Committee and Committee on Transportation and Infrastructure, both of which potentially have oversight jurisdiction.
Another potential leader on this is Rep. Don Beyer (D-Va.), the incoming chair of the Science Oversight subcommittee, who has spoken out in support of actions by state attorneys general to investigate Exxon.
