First Lady Michelle Obama joins President Obama at the food bill signing on Monday morning at a Washington school.

Excerpt from her speech:

"We can all agree that here in the wealthiest nation on earth, all children should have the basic nutrition they need to learn and grow and pursue their dreams. ... And that's why we've seen such a groundswell of support for these efforts ... From educators working to provide healthier school meals ... From doctors and nurses who know that unhealthy kids grow into unhealthy adults ... From business and labor leaders who know that we spend nearly $150 billion a year to treat these diseases ... From advocates and faith leaders who know that school meals are vital for combating child hunger ... "And from military leaders who tell us that when more than one in four young people are unqualified for military service because of their weight, childhood obesity isn't just a public health threat -- it's not just an economic threat -- it's a national security threat as well. These folks come at this issue from all different angles. But they've come together to support this bill ... And they know that in the long run, it won't just save money, it will save lives."
