Congressman Rahm Emanuel will resign his congressional seat on Friday in anticipation of joining President-elect Barack Obama's administration. Emanuel delivered the news in an automated call to constituents on Monday. "This is Congressman Rahm Emanuel. As you may have heard, President-elect Obama has asked me to be his new chief of staff and I have accepted this offer. Therefore, in the near future, I will be resigning from Congress. ... I also want you to know, it has been a privilege and an honor to serve as your representative for the last six years," he says in the taped call.
