Obama sits on Rosa Parks Bus in Detroit

President Barack Obama sits on the famed Rosa Parks bus at the Henry Ford Museum following an event in Dearborn, Michigan, on April 18, 2012. Rosa Parks refused to sit in the back of the bus on December 1, 1955 in Montgomery, Alabama, and this led to a bus boycott by African Americans. The bus is now considered a shrine in the civil rights movement. UPI/White House/Pete Souza
