A top health care adviser to President Obama is leaving the White House for health and family reasons.
Chris Jennings, also a health policy adviser during the Bill Clinton presidency, joined the Obama White House last year.
"It has been a great privilege to work with the President and his incredibly dedicated team on the Affordable Care Act," Jennings said in a statement.
He added: "It has been an honor to help ensure that the promise of affordable, quality health care embodied in this historic law becomes the reality for all Americans. This is the cause of my professional life and I look forward to making continued contributions to that end."
White House Chief of Staff Denis McDonough said in a statement, "we are all focused on reducing health care costs and implementing the Affordable Care Act. Nobody does so with more intellect, fortitude, and heart than Chris Jennings. Chris served the country at a time when he was needed most."
"An aide who spoke on condition of anonymity blamed a recent health scare and "other serious family considerations" for Jennings' departure. ...
"His arrival at the Obama White House was announced in July ahead of what proved to be a critical juncture for the law. The rollout of the program's primary website, HealthCare.gov, became a disaster as deep technical problems prevented people from signing up for coverage."
