In 2017, Cambridge Analytica company worked for a Ukrainian political party, while being under the investigation of U.S. Special Prosecutor Robert Mueller; the official looked into the interference with U.S. presidential election in 2017. Brittany Kaiser, the former worker of Cambridge Analytica said so as quoted by The Guardian.
"The release of documents began on New Year’s Day on an anonymous Twitter account, @HindsightFiles, with links to material on elections in Malaysia, Kenya and Brazil. The documents were revealed to have come from Brittany Kaiser, an ex-Cambridge Analytica employee turned whistleblower, and to be the same ones subpoenaed by Robert Mueller’s investigation into Russian interference in the 2016 presidential election", reads the article.
Kaiser passed the documents from her email and hard drives, and some were delivered to the U.S. Senate in April 2018.
“It’s so abundantly clear our electoral systems are wide open to abuse. I’m very fearful about what is going to happen in the US election later this year, and I think one of the few ways of protecting ourselves is to get as much information out there as possible,” Kaiser said.
"The unpublished documents contain material that suggests the firm was working for a political party in Ukraine in 2017 even while under investigation as part of Mueller’s inquiry and emails that Kaiser says describe how the firm helped develop a “sophisticated infrastructure of shell companies that were designed to funnel dark money into politics”, wrote the outlet.
