Congresswoman Alexandria Ocasio-Cortez is dinging Facebook, Microsoft and Google for "implicit" support of climate change denial in a letter addressed to the CEOs of the three tech companies.

Facebook, Microsoft and Google were "high-level" sponsors of the LibertyCon conference in Washington, D.C., earlier this month that hosted a session "denying established science on climate change," Ocasio-Cortez, D-N.Y., and Chellie Pingree, a Democratic Representative from Maine, said in the joint letter.
