This is one reason why the oath was a redo:
Yes, the conspiracy theorists were ready to pounce, but wait had already started to pounce. There is no doubt that Chief Justice Roberts flubbed the wording, just look at the video, so for precaution the oath was re-administered.
Chief Justice John Roberts has administered the presidential oath of office to Barack Obama for a second time, just to be on the safe side.
The unusual step came after Roberts flubbed the oath a bit on Tuesday, causing Obama to repeat the wording differently than as prescribed in the Constitution.
White House counsel Greg Craig said Obama took the oath from Roberts again out of an "abundance of caution."
The chief justice and the president handled the matter privately in the Map Room on Wednesday night.
