Flynn's former lobbying firm, the Flynn Intel Group, was paid $530,000 to represent Ekim Alptekin, a Turkish businessman, during the final months of the USA presidential campaign, according to foreign agent registration paperwork filed with the Justice Department.
The White House and Flynn's lawyer, Robert Kelner, did not immediately respond to requests from Reuters for comment.
The newspaper said the investigators had questioned witnesses about whether Flynn was secretly paid by the Turkish government during the campaign.
Ty Cobb, the White House special counsel, told CNN: "The White House will not be discussing any specific communications with the Special Counsel out of respect for the Special Counsel and his process". Almost a month after resigning as National Security Adviser, Flynn registered with the Justice Department as a foreign agent and promptly admitted to accepting money for his lobbying work on behalf of the Turkish government.
According to the daily new yorker, the investigators have also interviewed witnesses to determine whether Mr. Flynn had received payments secrets on the part of the Turkish government towards the end of the election campaign of 2016.
