As the nation observed both Martin Luther King Day and Barack Obama's second inaugural, the president left his mark on an artifact with deep significance for the civil rights movement.
After Obama was sworn in at the Capitol, the president and Supreme Court Chief Justice John Roberts inscribed the King family Bible. That's according to a White House official, who says the King family requested the inscription.
