While Trump has sought to dismiss these Russia ties as insignificant, or characterized the people involved in them as peripheral figures, it has now become clear that special counsel Robert S. Mueller III views at least some of them as important pieces of his sprawling investigation of Russian meddling in last year’s presidential campaign.
Documents released last week as part of Papadopoulos’s guilty plea show that Mueller’s team is deeply interested in the Trump campaign’s operations, including possible links to Moscow, at even the lowest levels. And Mueller’s interest in Russian contacts may extend to Trump’s business, as well, with the special counsel’s office recently asking for records related to a failed 2015 proposal for a Moscow Trump Tower, according to a person familiar with the request.
