It looks like he put himself into that situation on purpose. From https://www.theguardian.com/technology/2018/nov/30/facebook-lawsuit-six4three-documents-court-uk https://www.theguardian.com/technology/2018/nov/30/facebook-... “After coordinating for weeks with the DCMS committee, Mr Kramer traveled to the United Kingdom with documents he never should have had in the first place on his laptop for some unspecified business and checked into a hotel 1500ft away from parliament,” said Sonal Mehta, an attorney for Facebook. “He voluntarily went the 1500ft to parliament, showed up unannounced, and asked to see a member of parliament. He brought with him the confidential documents on his laptop and a thumb drive.” It almost seems he was looking for an excuse to make those documents public.
