White House advisor Chris Liddell will be Washington's nominee to be the next head of the OECD, an administration official said Friday, putting a Trump ally in the running to lead the association of advanced economies. Liddell, a dual US-New Zealand national, serves as a deputy chief of staff to President Donald Trump and has extensive international experience, the official said. He has held executive-level posts at Microsoft and General Motors and is an Oxford University graduate. The current secretary general of the Organisation for Economic Co-operation and Development, Angel Gurria, has announced he will not seek a fourth term. Selection of the group's next leader will kick off August 1, with members choosing Gurria's successor for a five-year term that would begin June 2021. jme/acb
