President Obama's Senior Advisor accidentally tweets the N-word

Dan Pfeiffer, a senior advisor to President Barack Obama, tweeted out what is probably the worst typo imaginable on Tuesday morning when he was debating the merits a statement about political polarization and how Americans consume the news.

He meant to tweet that the polarization was a "bigger" issue on the right. And, well, the "B" is right next to the "N" on the keyboard, so all of his followers were treated to a message containing the N-word.

Pfeiffer immediately apologized for the horrible error.
