These investigators have called the White House to produce documents about Michael Flynn, the former national security adviser to president Donald Trump, according to the daily, citing officials close to the investigation.
The Times reported that prosecutors have been investigating Flynn's business dealings with a Turkish-American businessman who worked with Flynn a year ago, and are trying to determine if the Turkish government was behind payments to Flynn.
Mr Alptekin has publicly denied that there was anything untoward about the payments, which funded a campaign to discredit Fetullah Gulen, a Muslim cleric said to be behind a failed coup in Turkey in July 2016.
Investigators also want to determine whether Flynn paid a Turkish businessman to help hide the source of the payments, which amounted to $530,000.
Mueller's team, investigating whether President Trump's campaign coordinated with Russian Federation to influence last year's election, have questioned witnesses close to the former three-star general about Flynn's work with firms tied to the Turkish government, the New York Times reported. His potential failure to register as a foreign agent could also carry a felony charge.
