The presidential swearing-in, a secular ordinance just like baptism: To be sure it sticks, Chief Justice Roberts swore in President Obama again out of “an abundance of caution.”

After the flub heard around the world, President Barack Obama has taken the oath of office. Again. Chief Justice John Roberts delivered the oath to Obama on Wednesday night at the White House - a rare do-over. The surprise moment came in response to Tuesday’s much-noticed stumble, when Roberts got the words of the oath a little off, which prompted Obama to do so, too.

Don’t worry, the White House says: Obama has still been president since noon on Inauguration Day.

But they didn’t to let conspiracy-mongers go away completely empty-handed:

The president said he did not have his Bible with him, but that the oath was binding anyway.
