In September 2015, Fusion GPS was hired by The Washington Free Beacon, a conservative political website, to do opposition research on Trump and other Republican presidential candidates. In spring 2016 when Trump had emerged as the probable Republican candidate, the Free Beacon stopped funding investigation into Trump.[25] From April 2016 through October 2016, the law firm Perkins Coie, on behalf of the Clinton campaign and the Democratic National Committee retained Fusion GPS to continue opposition research on Trump.[26][27][28] In June 2016, after the Democratic National Committee had been compromised and its emails began to be published online by Wikileaks, Fusion GPS retained Christopher Steele, a private British corporate intelligence investigator and former MI-6 agent, to research any Russian connections to Trump. Steele produced a 35-page series of memos from June to December 2016, which became the document known as the Donald Trump–Russia dossier.[26][29] Fusion GPS provided Marc Elias, the lead election lawyer for Perkins Coie, with the resulting dossier and other research documents.[27][28]
