Mueller Subpoenas Director For Cambridge Analytica

The Guardian reports:

A director of the controversial data company Cambridge Analytica, who appeared with Arron Banks at the launch of the Leave.EU campaign, has been subpoenaed by the US investigation into possible collusion between the Trump campaign and the Russian government.

A spokesman for Brittany Kaiser, former business development director for Cambridge Analytica – which collapsed after the Observer revealed details of its misuse of Facebook data – confirmed that she had been subpoenaed by special counsel Robert Mueller, and was cooperating fully with his investigation.

He added that she was assisting other US congressional and legal investigations into the company’s activities and had voluntarily turned over documents and data.
