Obama takes messed up oath again

Barack Obama has re-done some of the ceremony he took part in to become the US President, after one of his lines was messed up the first time around.

When Mr Obama repeated something called the oath of office on Tuesday, the word "faithfully" was in the wrong place.

American rules say it's important that every new president makes exactly the same promise.

So to be absolutely certain everything was done properly, President Obama took the oath again at the White House.

Mr Obama takes the oath the first time

Mr Obama joked that they were doing it again because "it was so much fun".

In the oath, the new president must promise to "faithfully execute the office of president of the United States".

But on Tuesday, when the Chief Justice of the US Supreme Court, John Roberts, read out the oath for Mr Obama to repeat, he moved the word "faithfully" to the end of sentence.

Mr Obama appeared to notice the mistake and hesitated, but Mr Roberts said it again so Mr Obama repeated it.

When the president said the words then, his wife Michelle was by his side, and millions of people across the world were watching.

Second attempt

When he took the oath the second time it was in the Map Room of the White House, in front of just a few people.

Mr Obama is not the first president to have to take the oath twice.

Two other presidents, Calvin Coolidge and Chester Arthur, had to do it again because of similar problems.
