Biden’s lawyers notified government agencies, and the Justice Department opened an investigation to see how the classified material got there and whether there were additional documents elsewhere in Biden’s possession. The person familiar with the second discovery said those materials were also turned over.
The White House did not immediately respond to requests for comment about the new set of documents. Earlier in the day, a White House spokeswoman declined to say whether additional materials had turned up in the searches.
Speaking about the first set of documents on Tuesday, Biden told reporters that he didn’t know what was in the materials, and that he was “surprised to learn that there were any government records that were taken there to that office.”
The White House has repeatedly reiterated that it is cooperating with the Justice Department and that Biden’s lawyers promptly turned over the materials after finding them. The materials also weren’t found at a private residence — a significant contrast to former President Donald Trump, who had sensitive materials seized by the FBI from his Florida estate earlier this year.
Still, Republicans have been quick to draw a line between the two situations, with many insisting that Trump has been treated unfairly.
