On a visit to an infrastructure project in Virginia, the President announced that the Chairman and CEO of Caterpillar told him that if the American Recovery and Reinvestment Act passes, his company would be able to rehire some of the 20,000 employees it has laid off in the last few weeks."No matter what you do, you can't pass a law that makes somebody do the right thing, right?" That was Mrs. Obama's message to a group of young people she met with on a visit to the Mary’s Center for Maternal and Child Care, a Washington, D.C. nonprofit that provides a range of social services.
