White House officials have been reviewing Flynn's contacts with the Russian ambassador and whether he discussed the possibility of lifting US anti-Russian sanctions once Trump took office, which could potentially be a violation of law forbidding private citizens from engaging in foreign policy. This was reported by Reuters.
Flynn is a retired US army general and former director of the Defense Intelligence Agency. An early supporter of Trump, he has been a leading advocate to improve US relations with Russia.
Flynn had initially denied discussing sanctions with the Russians in the weeks before Trump took office January 20.
When a Washington Post report emerged last week quoting officials saying the subject of sanctions had in fact come up, Flynn left open the possibility that he had discussed sanctions but could not remember with 100 percent certainty, an administration official said.
There was no indication from transcripts of Flynn's conversations that he had promised to lift the sanctions but rather he made more general comments about hoping for better US-Russian relations with Trump, the third official said.
Trump has yet to weigh in on the subject, promising to reporters on Friday that he would look into it. Reporters are expected to ask him about Flynn at a press conference with Canadian Prime Minister Justin Trudeau on Monday.
Earlier it was reported that Trump's adviser Flynn discussed reprieving from sanctions with Russian ambassador. However Flynn denies that he had discussed sanctions with Kislyak.
