A U.S. House committee investigating whether Russia has tried to influence U.S. public opinion on fossil fuels asked Facebook, Twitter and Alphabet on Wednesday to turn over information about Russian entities that may have bought anti-fracking advertisements.

House Science and Technology Committee Chairman Lamar Smith, a Texas Republican and climate change denier, asked the CEOs of the technology companies to turn over documents by Oct. 10 that detail the involvement of Russian-based or funded entities detected on their platforms, information on ads they purchased, and any communications concerning ads advocating for "so-called green initiatives."
