Michelle Obama helps harvest the White House garden

Michelle Obama was joined by school students from Arizona, California, Ohio and Washington, D.C. for the harvest of the White House Kitchen Garden on Tuesday.

"It's beautiful," the First Lady told them, "And just imagine that everything was just dirt just a few months ago."

They then started digging, harvesting lettuce, bell peppers, sweet potatoes and tomatoes, before enjoying a late lunch in the White House.
