"Trump has gone from insisting that he had nothing to do with Russia [View all]

to justifying his business efforts there"

“On at least 23 occasions since the summer of 2016, Mr. Trump has said either that he had ‘nothing’ to do with Russia, or that he has ‘no deals,’ no investments and no ‘business’ in Russia,”

"In 2008, Donald Trump Jr. told a real estate conference that Russians accounted for a significant part of the Trump’s business interests. “In terms of high-end product influx into the U.S., Russians make up a pretty disproportionate cross-section of a lot of our assets,” he said. “Say, in Dubai, and certainly with our project in SoHo, and anywhere in New York. We see a lot of money pouring in from Russia.”"

"Trump’s younger son reportedly made similar claims, telling author James Dodson in regards to golf-course financing, “Well, we don’t rely on American banks. We have all the funding we need out of Russia.”"
