(CNN) - White House Chief of Staff Rahm Emanuel said Monday that he still has his eyes on City Hall.
Should Mayor Richard Daley decide not to seek reelection, "one day I would like to run for mayor of the city of Chicago," Emanuel told PBS host Charlie Rose.
"That's always been an aspiration of mine," he said, according to a transcript of the interview.
Daley, who turns 68 this weekend, has been the city's mayor since 1989. Chicago's mayoral election is next year, but the Democratic politician has yet to announce whether he'll run again.
"I hope Mayor Daley seeks reelection. I will work and support him if he seeks reelection," Emanuel said.
Emanuel, who was elected to the House in 2002, said he misses the interaction he used to have with constituents.
"I miss being in the - when you were running the office, that touch with people," he said.
Emanuel insisted he plans to stay in his current job as long as President Obama wants him there. But when pressed if he'd stay on for four, or even eight, years if asked, Emanuel replied, "Well, I was being generous there a minute ago."
Emanuel, who has a reputation as a tough political infighter, is credited with helping Democrats take control of the House in 2006. He also worked on President Clinton's first presidential campaign and served as a White House adviser to Clinton.
