Intercepted Russian Communications Part of Inquiry Into Trump Associates

Mr. Manafort is among at least three Trump campaign advisers whose possible links to Russia are under scrutiny. Two others are Carter Page, a businessman and former foreign policy adviser to the campaign, and Roger Stone, a longtime Republican operative.

.. The Times reported that Mr. Manafort’s name had surfaced in a secret ledger that showed he had been paid millions in undisclosed cash payments. The Associated Press has reported that his work for Ukraine included a secret lobbying effort in Washington aimed at influencing American news organizations and government officials.

.. Mr. Stone, a longtime friend of Mr. Trump’s, said in a speech in Florida last summer that he had communicated with Julian Assange, the founder of WikiLeaks, the anti-secrecy group that published the hacked Democratic emails. During the speech, Mr. Stone predicted further leaks of documents, a prediction that came true within weeks.
