Senators want Facebook to address anti-Muslim speech

The group, led by Sen. Chris Coons, plans to send a six-page letter to Facebook today expressing "deep concern" and asking the social network to commit to better auditing and internal monitoring of its practices.

Driving the news: The letter, seen by Axios, cites some progress from Facebook, including a recently completed civil rights audit, but notes that the company "has not yet publicly studied or acknowledged the particular ways anti-Muslim bigotry manifests on its platform."

• The letter has more than a dozen signatories, including Coons, Richard Blumenthal, Dick Durbin, Mark Warner, Amy Klobuchar and Elizabeth Warren.
