Former White House national security adviser Michael Flynn has expressed worries about the potential legal exposure of his son, Michael Flynn Jr., who, like his father, is under scrutiny by special counsel Robert Mueller.
The special counsel is looking into Russian meddling in the 2016 presidential election campaign.
Interviews conducted by special counsel investigators have included questions about the business dealings of Flynn and his son, reported CNN.
Flynn Jr., who served as his father's chief of staff and top aide, was active in his father's consulting and lobbying work at their firm, Flynn Intel Group.
Flynn's business dealings have been the subject of federal investigation since November 2016.
Flynn is also under legal scrutiny by Mueller's team for undisclosed lobbying that he did during the presidential campaign on behalf of the Turkish Government, CNN reported.
Former Trump campaign officials Paul Manafort and Rick Gates already face charges relating to their undisclosed foreign lobbying, for Ukraine.
Special counsel Robert Mueller has interviewed several White House former and current officials, including former White House chief of staff Reince Priebus and ex-White House press secretary Sean Spicer, according to the reports.
