WASHINGTON-- President Barack Obama is likely to tap deputy national security adviser Denis McDonough his next chief of staff, a source told the Sun-Times and multiple outlets are reporting.

McDonough and Obama have a strong personal relationship with ties going back to the 2008 presidential campaign where McDonough was a foreign policy advisor.

The new chief of staff follows Jack Lew, who Obama has nominated to be Treasury Secretary. Lew replaced Bill Daley; before Daley advisor Pete Rouse was interim chief of staff, taking over after first chief of staff Rahm Emanuel departed to run for mayor of Chicago.
