This week, members of Special Counsel Robert Mueller's team questioned a person who was a business associate of the Trump Organization, involved in recent deals conducted overseas, several people with knowledge of the matter told McClatchy DC.
Mueller's team arrived at the person's house unannounced, with subpoenas for electronic records and sworn testimony, McClatchy DC reports. This person was involved with several transactions related to President Trump's efforts to do business in foreign countries, and the investigators primarily wanted information on the person's interactions with Trump's personal lawyer Michael Cohen.
Cohen left the Trump Organization in January 2017, but prior to that he had been part of attempted and completed business deals in Russia, Georgia, and Kazakhstan. Last month, The Washington Post reported that Mueller's team has been looking into a hotel deal with a Moscow developer during the 2016 campaign, including a letter of intent from the businessman that Cohen delivered to Trump.
