Here is audio of President Barack Obama retaking the Presidential Oath of Office on January 21, 2009. He did so as a result of a flub that took place on Inauguration Day when Chief Justice John Roberts mixed up the words of the Oath, and Obama repeated it incorrectly. Roberts again administered the Oath at the White House on the evening of January 21, 2009. No video was allowed, but this audio has been released. . . . . (Listen to audio)
