WASHINGTON, Jan 23 (Reuters) - The White House said on Monday that a search by the Justice Department of President Joe Biden's home on Friday had been carried out after a "voluntary, proactive offer" by his personal lawyers to the department. It was the latest in a string of discoveries of classified documents at Biden's Wilmington home and at a temporary office at the University of Pennsylvania. "This was a voluntary, proactive offer by the president's personal lawyers to DOJ to have access to the home," said White House spokesperson Ian Sams. Sams declined to provide more clarity on the exact content of the materials taken from the Wilmington house. Biden had been kept informed throughout this process, the White House said.
