Daley is now returning to Chicago, his home town.
"Daley gave his letter of resignation to the president in a private meeting in the Oval Office last week, recounting the administration's successes of his one year on the job and saying it was time for him to return to his hometown of Chicago," said The Chicago Tribune, which was the first one to break the news.
