"Phone records and intercepted calls show that members of Donald J. Trump’s 2016 presidential campaign and other Trump associates had repeated contacts with senior Russian intelligence officials in the year before the election, according to four current and former American officials."

"The call logs and intercepted communications are part of a larger trove of information that the F.B.I. is sifting through as it investigates the links between Mr. Trump’s associates and the Russian government, as well as the hacking of the D.N.C., according to federal law enforcement officials. As part of its inquiry, the F.B.I. has obtained banking and travel records and conducted interviews, the officials said.""
