Michael T. Flynn, who was fired after just 24 days on the job, was one of the first Trump associates to come under scrutiny in the federal probe now led by Special Counsel Robert Mueller into possible collusion between Moscow and the Trump campaign, NBC News wrote.
Mueller is applying renewed pressure on Flynn following his indictment of Trump campaign chairman Paul Manafort, three sources familiar with the investigation told NBC News.
The investigators are speaking to multiple witnesses in coming days to gain more information surrounding Flynn's lobbying work, including whether he laundered money or lied to federal agents about his overseas contacts, according to three sources familiar with the investigation.

Flynn's son, Michael G. Flynn, who worked closely with his father, accompanied him during the campaign and briefly worked on the presidential transition, could be indicted separately or at the same time as his father, according to three sources familiar with the investigation.
If the elder Flynn is willing to cooperate with investigators in order to help his son, two of the sources said, it could also change his own fate, potentially limiting any legal consequences.
