NEW DELHI: FBI investigators have found additional classified documents from US President Joe Biden’s residence in Wilmington after conducting a 13-hour search of the home.

Bob Bauer, the President’s personal attorney, said in a statement that during the search, “Department of Justice took possession of materials it deemed within the scope of its inquiry, including six items consisting of documents with classification markings and surrounding materials, some of which were from the President’s service in the Senate and some of which were from his tenure as vice president.”

The federal search of BIden’s home, while voluntary, marks an escalation of the probe into the president’s handling of classified documents and will inevitably draw comparisons to his predecessor, former President Donald Trump – even if the FBI’s search of Trump’s residence was conducted under different circumstances; CNN reported.

The total number of classified documents found in the residences and private offices of Biden has now increased to nearly a dozen and a half. All documents, including from his term as vice president from 2009 to 2016, have now been taken into possession of federal agents.

Former US President Donald Trump also faces a similar probe over his alleged mishandling of hundreds of classified documents at his Florida Mar-a-Lago residence and his alleged failure to comply with a subpoena.

The lengthy search and subsequent discovery of more documents is a political headache and a possible legal liability for Biden, as he prepares to declare whether he will run for a second term.
