Here's a quick glimpse at what happened this week on WhiteHouse.gov: President Obama Speaks to Troops at Fort Bliss: Last Friday, two years after his visit to Fort Bliss that marked the end of the combat mission in Iraq, President Obama returned to speak to the troops . Now, when I was here last, I made you a pledge. I said that, as President, I will insist that America serves you and your families as well as you've served us. And there again, I meant what I said. Because part of ending wars responsibly is caring for those who fought in it. That’s why I wanted to come back to Bliss on this anniversary to reaffirm our solemn obligations to you and your families. You see, we may be turning a page on a decade of war, but America's responsibilities to you have only just begun.

President Obama Meets with Victims of Hurricane Isaac: On Monday, President Obama visited St. John’s Parish in Louisiana to understand the damage from Hurricane Isaac and meet with officials responding to the disaster. The President highlighted the “extraordinary work” done by local first responders who worked around the clock to rescue residents stranded by high water in a place that hadn't flooded in 17 years. "Some of the folks that we just walked by literally had to be saved by boat. They were in their homes, trapped. The waters came in so quickly," he said. "But because of the great work of law enforcement, National Guard, Coast Guard, making sure that folks were out in rescue mode rapidly, even in some cases at risk of their own lives, no lives were lost."
