The FBI in late December reviewed intercepts of communications between the Russian ambassador to the United States and retired Lt. Gen. Michael T. Flynn — national security adviser to then-President-elect Trump — but has not found any evidence of wrongdoing or illicit ties to the Russian government, U.S. officials said.

The calls were picked up as part of routine electronic surveillance of Russian officials and agents in the United States, which is one of the FBI’s responsibilities, according to the U.S. officials, who spoke on the condition of anonymity to discuss counterintelligence operations.

Nonetheless, the fact that communications by a senior member of Trump’s national security team have been under scrutiny points up the challenge facing the intelligence community as it continues its wide-ranging probe of Russian government influence in the U.S. election and whether there was any improper back-channel contacts between Moscow and Trump associates and acquaintances.

Although Flynn’s contacts with Russian Ambassador Sergey Kislyak were listened to, Flynn himself is not the active target of an investigation, U.S. officials said. The Wall Street Journal reported Sunday that U.S. counterintelligence agents had investigated the communications between Flynn and Kislyak.
