Speaking on her first overseas trip as Attorney General of the US, Lynch said "the issues we have talked about are the most challenging for those of us who work in areas of law enforcement" and that "practical progress" had been made.
Inevitably, journalist questions were exclusively about the US' pursuit of FIFA officials on charges of massive corruption.
"With respect to the FIFA investigation we are not able to comment further on the nature of other individuals who may or may not be under investigation. This is an ongoing matter, it is an open case, so we will not be speaking through the courts," Lynch said.
"The investigation is ongoing... I would like to reiterate again my thanks to the Swiss authorities... this is yet another example of international cooperation.
"I don't have a comment on Mr Blatter's decision to step down except to say that we certainly hope that the organization is able to move forward in a way that is supportive of its goals which are the promotion and regulation of a truly wonderful sport," Lynch said.
Following the meeting the EU and US released a joint statement which can be read here.
