Many of these people didn’t work within Biden’s office throughout Obama’s tenure as president, but they have extensive campaign experience ranging from political consulting to communications, according to sources with direct knowledge of the matter.

Since their time in the Obama White House, some of these aides have gone on to work on Hillary Clinton’s 2016 presidential campaign and later helped Democrats retake the U.S. House of Representatives during the 2018 congressional midterm elections, these people said.

Numerous former Obama White House advisors who have been brought on to work with Biden’s team, have yet to hear where the campaign will be headquartered. But they expect it will be either in Delaware or Pennsylvania. Biden was born in Scranton, Pennsylvania and as a Senator, represented the First State for over three decades.
