A report released Friday by top cyber-security experts concludes, as did Special Counsel Robert Mueller, that the 2016 Trump presidential campaign did not secretly communicate with the Russian government via a computer server belonging to Russia’s Alfa Bank.
In the report by the cyber consulting firm Ankura, cyber experts determined that the communication from Alfa Bank to servers on the U.S. East Coast were going to a company that runs marketing activities for several global hotel chains, including, for a number of years, the Trump Hotels - not servers owned or operated by the Trump campaign.
