After much speculation, Rahm Emanuel will announce tomorrow that he is leaving his post as President Obama's first chief of staff, National Journal has confirmed.
Emanuel, a former congressman and White House official in the Clinton Administration, will run for mayor of Chicago and has already selected a campaign manager, according to The Atlantic's Marc Ambinder. He's likely to face a crowded Democratic primary.
Known for his combative style and salty language, Emanuel cut a large figure in Washington where he quickly ascended the Democratic leadership in the House and was the architect of his party taking back the chamber in 2006. There's no immediate word on his successor but speculation has centered on Pete Rouse, a top White House official. Other names include Tom Donilon, chief of staff for the National Security Advisor, and Ron Klain, chief of staff for Vice President Joe Biden. The Atlantic's Ambinder places Rouse as the most likely pick allowing that it could be someone else entirely.
