Do you know why the President used two Bibles for his swearing-in? One is Abraham Lincoln's because he signed the Emancipation Proclamation freeing slaves 150 years ago, and one is Martin Luther King Jr.'s because he gave his "I Have a Dream" speech 50 years ago. To hear Dr. King give his speech, go to KidLinks>Homework Help>Current Events>Info Track Student and enter "I have a dream speech" in the search box.
