Obama Marks Fall of Berlin Wall as 'Rebuke of Tyranny'

President Obama, saying Nov. 9, 1989, was a day he will "never forget," expresses regrets for not being able to attend the celebration of the 20th anniversary of the fall of the Berlin Wall.

President Obama on Monday marked the 20th anniversary of the fall of the Berlin Wall in a video message broadcast before a huge crowd in Germany, calling the destruction of the wall a "rebuke of tyranny."

The video message was aired after Secretary of State Hillary Clinton, who led the U.S. delegation in Germany for the celebration, addressed the crowd.
