Federal investigators conducted a search Wednesday of President Joe Biden’s vacation home in Rehoboth, Del., as part of their ongoing probe into his handling of classified documents, officials said.

Bob Bauer, Biden’s personal lawyer, said in a statement that the president’s team did not seek to provide advance notice of the operation. But he confirmed the search by the Department of Justice was taking place after it was reported by CBS News.

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

The search is part of a special counsel investigation into Biden’s handling of the classified materials found in November at his office in Washington and in December and January at his home in Wilmington. In late January, a 13-hour search of Biden’s home recovered additional classified items.
