Ron Klain is responsible for preparing Mr Biden's emerging team for government, before the January 20 inauguration. Until now, this task was complicated by the absence of a formal transition process, following a long period of deliberation by the General Services Administration, the government body tasked with legally confirming the election result. Mr Klain was formerly the chief of staff for Joe Biden when he was vice-president, as well as having led the Ebola crisis response under president Obama.
