A court filing in January revealed that Paul Manafort had shared unspecified polling data with Konstantin Kilimnik during the 2016 election campaign.

House investigators ask Manafort and his associates for information regarding the sharing of election data with foreign entities during the campaign, but also appear to home in on former employees of British political consulting firm Cambridge Analytica. That company harvested data from social media companies to micro-target voters while working for the Trump campaign during the 2016 election.

The House Judiciary Committee is asking the company for information regarding whether it received or shared election-related information from foreign countries.
