Facebook is dispatching Sheryl Sandberg, its powerful chief operating officer, to Washington, D.C., this week, as the company attempts to contain the political fallout from revelations that Russian agents spread disinformation on the social network.

The house call to the nation’s capital — confirmed to Recode on Tuesday by multiple source — comes as Facebook prepares to join its tech peers and testify at two public congressional hearings in November that are focused on the Kremlin’s suspected meddling in the 2016 U.S. presidential election.
