McDonough expected to be named White House chief of staff

Deputy National Security Adviser Denis McDonough is expected to be named White House chief of staff, according to a source familiar with the process.

President Obama is still said to be weighing a final decision on who might replace current chief of staff Jack Lew, whom Obama has nominated for Treasury secretary. But others familiar with the process say they expect him to tap McDonough in the coming days.

McDonough, 43, has been with Obama for years, serving in his Senate office and going on to work on the 2008 campaign. He was heavily involved in some of Obama's major decisions on foreign policy, including the end of the war in Iraq and the drawdown of troops in Afghanistan.
