Investigators are demanding documents to the White House

Investigators working for special counsel Robert Muller have asked the White House for documents on former National Security Adviser Michael Flynn as they examine whether he was secretly paid by the Turkish government to lobby against a critic of Turkish President Recep Tayyip Erdogan.

But the investigation team led by special counsel Robert Mueller want to know if the Turkish government was behind the payments or if Mr Alptekin was bribed to hide the source of the money, according to the New York Times.

They have sought related documents from the White House and have asked related information from witnesses during interviews, a significant development in the Russian Federation investigation.

What it also indicated was that Mueller was not focussed only on Flynn's contacts with Russians or his lying about them but was at his financial dealings.

Flynn's business, Flynn Intel Group, worked with a Turkish-American businessman who paid the company $530,000 to "discredit an opponent of the Turkish government who has been accused of orchestrating last year's failed coup in the country". Flynn was forced to resign in February after it was reported that he misled Vice President Mike Pence about the nature of his phone calls with the Russian Ambassador to the US, Sergey Kislyak.

Prosecutors suspect that Mr Flynn may have received secret payments from the Turkish government during the presidential campaign, it is claimed.

The White House and Flynn's lawyer, Robert Kelner, did not immediately respond to requests from Reuters for comment.

While Mr Mueller steps up his investigation, Donald Trump has again angrily denied that his campaign team colluded with the Kremlin.

"We've said before we're collaborating with the special counsel on an ongoing basis", he told the newspaper."It's full cooperation mode as far as we are concerned", he said, according to the report.
