Many questions remain about President Trump’s familiarity during the 2016 campaign with a proposed development project in Moscow. Those questions were stoked in recent days thanks to BuzzFeed News’s claim last week that Trump told his longtime personal attorney Michael Cohen to lie about the extent of those conversations — a claim denied by special counsel Robert S. Mueller III’s office. The questions were amplified when one of Trump’s current attorneys, former New York mayor Rudolph W. Giuliani, claimed over the weekend that discussions about the project may have continued until Election Day. (Giuliani later walked back this assertion.)
