The BuzzFeed asked the FTI Consulting, a business advisory company, to find verification of the Trump's dossier. Anthony Ferrante, a former FBI agent, who currently works with the FTI, has been traveling across the world over the last six months to find documents and hold meetings within the mission, according to the Foreign Policy online magazine.
The media outlet initially used the FTI within the case with Russian tech expert Aleksej Gubarev, who questioned his name included in the Trump's dossier. However, the case has since extended, the magazine reported.
Ferrante, the FTI Consulting, and the FBI refused to comment on the issues, according to the magazine.
In January 2017, the BuzzFeed news outlet issued 35 pages of a dossier claiming that the Russian government had both collected compromising information about the former Republican candidate and was engaged in assisting Trump in his presidential bid. According to media reports, Glenn Simpson, co-founder of the Fusion GPS company, hired former UK spy Christopher Steele to compile the dossier, funded by Hillary Clinton campaign.
