			 Nabors, a former deputy director of the White House's Office of 
			Management and Budget and a former head of legislative affairs, has 
			been a top negotiator for the administration in talks with lawmakers 
			over budget and deficit issues. 
 			Alyssa Mastromonaco, another deputy chief of staff and a longtime 
			Obama aide, is also thinking about an exit, sources said.
 			The potential departures come amid a broad staff shake-up, with 
			long-serving Obama counselor Pete Rouse leaving soon. John Podesta, 
			a former chief of staff to President Bill Clinton, will join the 
			White House in January.
 			"Neither Rob nor Alyssa have plans to leave and reports to the 
			contrary are inaccurate," White House spokeswoman Jamie Smith said 
			in an email.
 			Sources outside the administration said Nabors has indicated he is 
			ready to move on, and an administration official said Mastromonaco 
			was contemplating an exit. 			
			
			 
 			"After five and a half years, the thought has crossed her mind," the 
			official said.
 			The two senior aides work under chief of staff Denis McDonough, who 
			has been in the top White House job for roughly a year.
 			Nabors is deputy chief of staff for policy and Mastromonaco is 
			deputy chief of staff for operations, responsible for planning 
			presidential events, hiring staff, and overseeing the White House 
			campus. Many of Obama's senior advisers who worked in his 
			administration and on his 2008 campaign have left. Climate and 
			energy adviser Heather Zichal departed in the fall. David Axelrod 
			and David Plouffe, who helped engineer his 2008 and 2012 electoral 
			victories, left Obama's official orbit after the last presidential 
			campaign.

			If the two deputies depart, it would leave a diversity hole in a 
			group of senior Obama advisers that critics say has an overabundance 
			of white men.
 			Nabors, who is African-American, worked in Bill Clinton's budget 
			office and then spent several years on Capitol Hill, serving as 
			staff director of the House of Representatives Appropriations 
			Committee, where he honed his budget skills.
 			"He understands the technical nature of budgeting in a way that few 
			people understand it," former Representative David Obey, a one-time 
			chairman of the House appropriations committee, told Reuters in an 
			interview last year.
 			"Rob is very much a person who wants to be in the background. He's 
			not somebody who's looking for a camera or a microphone. He just 
			wants to facilitate getting the job done."
 			The U.S. Senate passed a two-year budget deal on Wednesday to ease 
			automatic spending cuts and reduce the risk of a government 
			shutdown.
