WASHINGTON -- When President Obama takes his symbolic oath of office today, the 57th presidential inauguration, he'll do so on two bibles, each of historical significance.
One belongs to Martin Luther King Jr., the other to Abraham Lincoln, a symbolic testament to the struggles for equality in the nation honoring the emancipation of slaves and King's fight for equal rights for African Americans.
On March 4, 1865, African Americans took part in the Inaugural parade for the first time in history. That was as part of Abraham Lincoln's Twentieth Inaugural Ceremonies.
It was 50 years ago that King delivered his historic "I have a dream" speech at the Lincoln Memorial. Today is also the federal holiday honoring the assassinated civil rights leader.
