Also giving evidence to the committee is Edward Lucas, a security expert from the Centre for European Policy Analysis.
Labour's Chris Matheson tells him the committee heard from Facebook that there had been little Russian "meddling" in the EU referendum.
"This is something we should be able to get empirical data on, but we can't because we don't have the cooperation of Facebook," says Edward Lucas.
"We need transparency about advertisements on all the communication service providers."
