I saw the president make the tough calls in the Situation Room - and today, our troops in Iraq have finally come home so America can do some nation building here at home. That was the change that we believed in. That was the change we fought for. That was the change President Obama delivered.

As we move forward, I am looking for a new leader of the Chicago Police Department to address the problems at the very heart of the policing profession. The problem is sometimes referred to as "the thin blue line." The problem is other times referred to as "the code of silence." It is this tendency to ignore. It is the tendency to deny. It is the tendency, in some cases, to cover up the bad actions of a colleague or colleagues.

Nearly losing my life made me want to live my life.

In the White House, you can be on the pitcher's mound or you can be in the catcher's position. Put points on the board. Show people you can govern. Deliver on what you said you were going to deliver on.

Whose leadership, whose judgment, whose values do you want in the White House when that lands like a thud on the oval office desk?

I think that every country presents its own particular challenges, different cultures, different histories, different religions, different people. And different ethnic make-ups in those countries present different challenges.

We're proud of the work we're doing to make Chicago a great city for people of all ages. Nothing's more important than keeping in mind the needs of older adults - and how valuable a role they play in improving the city, based on their amazing collective talent and wisdom.
