It appears that the government of Turkey was spectacularly successfully in compromising FBI, CIA, DEA, DIA and DOS operations, and was also able to mount other espionage programs that allowed Turkish interests to obtain assorted military and WMD technology know-how, and garner US and Israeli military support for its bloody internal struggle against its significant and much maligned Kurdish population/opposition.

Details here, but very briefly I mention "The illicit drug trade provided an endless source of funds to pay for WMD components"

IMO: I take all this as confirmation of previous suggestions that both Turkey and the EU have far too many problems for moves to Turkish membership or affiliation to be furthered at this time. For a start there is the dodgy airbus and its new links to French arms deals with China.
