The New York Times reported that law enforcement and intelligence agencies intercepted calls and phone records showing Donald Trump's presidential campaign aides, as well as other associates, having repeated contact with senior Russian intelligence officials in the year before the election.

The report names four people close to Trump — including Michael Flynn, who recently stepped down as national security adviser — in the FBI's inquiry into links between Trump associates and the Russian government. Officials named Trump's former campaign chairman Paul Manafort as one of the associates on the calls but did not identify anyone else on the calls, the Times reported.

Still, the officials said the FBI has looked into at least two other people close to Trump: Carter Page, a businessman and former foreign policy adviser to the campaign and Roger Stone, a veteran GOP operative.

Dmitry Peskov, spokesman for Russian President Vladimir Putin, told reporters in Moscow on Wednesday that the reports were "absolutely groundless."

"Let us not believe in what media say, for nowadays it is very difficult to tell actual news from fake ones," he said, according to the Russian news agency TASS. "Let us not rely on unidentified sources. These reports are absolutely groundless, not based on any facts," he added.
