Last Friday, President Obama visited a Walmart in Mountain View, California, that's making big changes to the way it uses energy.
"A few years ago, you decided to put solar panels on the roof of the store," he explained. "You replaced some traditional light bulbs with LEDs. You made refrigerator cases more efficient. And you even put in a charging station for electric vehicles."
In this week's address, First Lady Michelle Obama honored all mothers for Mother's Day and offered her thoughts, prayers, and support in the wake of the unconscionable terrorist kidnapping of more than 200 Nigerian girls.
