Two Democrats Want More Election Answers from Facebook, Twitter

Two senior U.S. Democratic lawmakers asked Facebook and Twitter to answer questions about potential Russian involvement in social media campaigns that urged release of a Republican memorandum alleging surveillance abuses at the FBI, saying the companies had provided insufficient responses so far. The letter was the latest effort by Democrats, in the minority in both the U.S. Senate and House of Representatives, to press social media companies on whether the Kremlin has used their platforms to meddle in U.S. politics.
