WASHINGTON: Despite public promises of cooperation from Facebook and other social media companies, congressional investigators are battling over how much data the companies should hand over to them on Russian efforts to influence the 2016 US presidential election. 

Congressional sources said this week that Facebook Inc has been slow to cooperate. The company and others have said they are turning over information, but also that they are legally obligated to protect their users' privacy.
