Who was it who said he "hires only the best people"?

I think Mueller will have the last laugh about that.

A gold trader who is close to Turkish President Recep Erdogan is now cooperating with federal prosecutors in a money-laundering case, according to two sources with knowledge of the matter, and legal experts say prosecutors may be seeking information about any ties between the Turkish government and former National Security Advisor Mike Flynn.

Special counsel Robert Mueller is investigating whether Erdogan offered Flynn upwards of $15 million during the presidential transition in December to use his upcoming position as national security advisor to return his top political rival, Fethullah Gulen, from the U.S. to Turkey.
