WASHINGTON-President Barack Obama will tap long-time advisor Denis McDonough as the new White House chief of staff on Friday, a White House official said.
McDonough will become Obama's fifth top chief of staff, following Rahm Emanuel, interim chief of staff Pete Rouse, Bill Daley and Jack Lew.
David Simas is returning to the White House after departing for the Obama campaign in Chicago. Simas, who had worked closely with Obama top strategist David Axelrod, returns as the Deputy Senior Advisor for Communications and Strategy.
The official said, "Denis has been one of the President's closest and most trusted advisors for nearly a decade, dating back to when he helped set up then Senator's Barack Obama's Senator office. He has relied on his intellect and good judgment ever since-- most recently as a member of the President's national security team. In that capacity, Denis has played a key role in all of the major national security decisions -- from ending the war in Iraq to winding down the war in Afghanistan; from our response to natural disasters in Haiti and Japan; to the repeal of 'Don't Ask, Don't Tell.'
"As a veteran of Capitol Hill, Denis understands the importance of reaching across the aisle to make progress for the American people --whether it's on jobs and economy, health care or education, reducing the deficit or addressing climate change."
