Standing before reporters in February, President Trump said unequivocally that he knew of nobody from his campaign who was in contact with Russians during the election. Attorney General Jeff Sessions has told the Senate the same thing. Court documents unsealed this week cast doubt on both statements and raised the possibility that Mr. Sessions could be called back to Congress for further questioning. The special counsel, Robert S. Mueller III, unsealed his first charges Monday in a wide-ranging investigation into Russian attempts to disrupt the presidential election and whether anyone close to Mr. Trump was involved. Records in that case show that George Papadopoulos, a foreign policy adviser, had frequent discussions with Russians in 2016 and trumpeted his connections in front of Mr. Trump and Mr. Sessions. For months, journalists have revealed evidence that associates of Mr. Trump met with Russians during the campaign and the presidential transition. But the court documents represent the first concrete evidence that Mr. Trump was personally told about ties between a campaign adviser and Russian officials.
At a March 31, 2016, meeting between Mr. Trump and his foreign policy team, Mr. Papadopoulos introduced himself and said “that he had connections that could help arrange a meeting between then-candidate Trump and President Putin,” according to court records.
“He went into the pitch right away,” said J. D. Gordon, a campaign adviser who attended the meeting. “He said he had a friend in London, the Russian ambassador, who could help set up a meeting with Putin.”
Mr. Trump listened with interest. Mr. Sessions vehemently opposed the idea, Mr. Gordon recalled. “And he said that no one should talk about it,” because Mr. Sessions thought it was a bad idea that he did not want associated with the campaign, he said.
