FBI agents on Wednesday searched the Rehoboth, Delaware, beach home of President Joe Biden as part of an investigation into the previous discovery of classified documents at other locations connected to the president, his personal lawyer said.

The agents arrived Wednesday morning at Biden’s home in Rehoboth.

The Department of Justice is investigating the discovery of classified documents at a private office in Washington, D.C., that Biden had used while a private citizen, and at his residence in Wilmington, Delaware. The FBI previously searched both of those locations.

Biden’s lawyer, Bob Bauer, in a statement said, “Today, with the President’s full support and cooperation, the DOJ is conducting a planned search of his home in Rehoboth, Delaware.”

“Under DOJ’s standard procedures, in the interests of operational security and integrity, it sought to do this work without advance public notice, and we agreed to cooperate,” Bauer said.

“The search today is a further step in a thorough and timely DOJ process we will continue to fully support and facilitate. We will have further information at the conclusion of today’s search,” Bauer said.

The White House did not immediately respond to a request for comment from CNBC.
