MSNBC host Rachel Maddow rushed to defend President Joe Biden after classified documents were discovered inside Biden's former office at a Washington think tank.

What is the background?
Personal attorneys for Biden discovered "roughly 10" classified documents inside Biden's office at the Penn Biden Center for Diplomacy and Global Engagement on Nov. 2.

The subject of the documents was not revealed, nor was their level of classification. Richard Sauber, special counsel to Biden, said the White House notified the National Archives about the documents on the same day they were discovered. The documents were turned over to the agency the next day.

The classified documents were allegedly mixed together with non-classified documents. It's not clear if an investigative team conducted a search of the office to determine whether there were more classified documents stored at the office.
