Counting the numbers of troops is not going to define our success here.There is no military success, ultimately, to Afghanistan. The Afghans themselves are going to define what happens here. And we have to convince ourselves that we have a strategy in place that empowers them to do that and that is realistic in what our expectations are from them and on what schedule.

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.

And it's time as a country that we have an assault weapon ban.

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.

The Afghan - obviously the parties will decide which course of action. The most important there, get a government that is seen as legitimate to the people and has the credibility to be a partner in the effort to secure Afghanistan so it's not a haven for al Qaeda or other type of terrorists or international terrorist organizations.

Things happened there that I don't think are the finest hours for anybody, whether it was a journalist, the legal system or, in that case of the political system, who would say that was an example of when Washington worked best.

At some point, deliberation begins to look more like indecisiveness which then becomes a way of emboldening our enemies and allies and causing our allies to question our resolve. So we shouldn't let one component of this determine our national security here which depends on providing an Afghanistan which denies a safe haven to terrorists as well as stabilizing Pakistan. Those are our two national security interests at stake in Afghanistan.
