Podesta declined to be interviewed for this story, and a Clinton spokesman also would not comment on his prospective role in her 2016 campaign. But several people close to her operation spoke about Podesta on the condition of anonymity, because they were not authorized by Clinton's team to do so publicly on the record.
A wiry Chicagoan with a quirky, sometimes dark, sense of humor, Podesta accepted the post in Obama's White House on the condition that he would only stay for one year. White House officials said it wasn't clear at the time that Podesta intended to work for Clinton when he left.
"What John does on his personal time is not my matter," said Denis McDonough, the White House chief of staff who repeatedly tried to lure Podesta back to the West Wing before finally succeeding in late 2013.
For Obama and Clinton, affiliating with Podesta " a sharp political tactician and progressive policy wonk " is a way to signal to critics and wary supporters they are willing to recalibrate and learn from past mistakes.
Obama brought on Podesta after the disastrous rollout of his health care law, a deeply challenging stretch that sparked questions about his competence and that of his tight-knit inner circle. Several current and former White House officials said Podesta quickly injected more depth into strategy discussions and would often play devil's advocate, pushing the team to consider things not on their radar.
For Clinton, bringing on Podesta is widely viewed as an effort to avoid the disorganization and backbiting that plagued her 2008 bid. He wasn't directly involved in that run. Though Podesta's title is expected this time to be something akin to campaign chairman, he is expected to have a hand in day-to-day operations and is seen as one of the few staff members who can be candid with both Hillary and Bill Clinton.
It was Podesta who was tasked with navigating the Clintons through the numerous investigations, personal embarrassments and Clinton's impeachment hearing " experiences that deepened the couple's trust in him.
