Input: Michael Flynn  is reportedly concerned that  his  son  Michael Flynn Jr.  could get wrapped up in Robert Mueller's Russia investigation.
 The younger Flynn  worked closely with  his  father during  his  undisclosed communications with Russia and Turkey.
 Former national security adviser Michael Flynn  is reportedly concerned that  his  son  Michael Flynn Jr.  could get wrapped up in special counsel Robert Mueller's Russia investigation.
A CNN report citing multiple sources said that  Flynn 's concern could shape the way  he  responds to Mueller's probe  which seeks to determine whether President Donald Trump's campaign colluded with Russia to tilt the 2016 election in Trump's favor.  Flynn 's wife Lori is also concerned about  their son 's possible legal exposure  the report said.
Mueller already has enough evidence to bring charges against both Flynns  according to an NBC News report from Sunday. The evidence relates to the senior  Flynn 's undisclosed lobbying efforts for a businessman with ties to the Turkish government in 2016  when he was also an adviser on the Trump campaign.
 Flynn Jr.  was  his  father's chief of staff  and appears to have worked closely with  him  in  his  lobbying work. According to some legal experts  Mueller's focus on the younger  Flynn  could be an attempt coerce his father into cooperating with the investigation.
Investigators are also looking at  Flynn 's alleged participation in talks to turn over to Turkey a Turkish cleric living in exile in Pennsylvania.  Flynn  has denied through a spokesperson that those conversations took place.
 Flynn  resigned from  his  White House post in February after it emerged that  he  misled Vice President Mike Pence about his communications with Russian officials.
It is unclear whether Mueller will go through with indictments for either  Flynn . In the meantime   Flynn Jr.  is maintaining an optimistic front  telling  his  critics on Twitter  "the disappointment on your faces when I donât go to jail will be worth all your harassment."
