Second batch of classified Biden documents found

US President Joe Biden's aides have found a fresh batch of classified government records at a second location, in a growing political embarrassment for the White House, reports BBC. 

The first cache was found at a private office in Washington DC that Mr Biden used after his vice-presidency.

The matter is under review by the US Department of Justice.

Donald Trump is facing a criminal investigation for allegedly mishandling classified files.

It was not yet clear on Wednesday when or where the additional tranche of files was found by Biden aides.

The original batch of about 10 documents was discovered in November at the Penn Biden Center, a think tank near the White House, but only came to light this week.

Those papers reportedly include US intelligence memos and briefing materials related to Ukraine, Iran and the United Kingdom.

The White House has not yet commented on the newly discovered batch. Earlier on Wednesday, White House press secretary Karine Jean-Pierre declined to answer questions about the first cache of files during her daily press briefing.

"This is under review by the Department of Justice" she said. "I'm not going to go beyond what the president shared yesterday."

Mr Biden said on Tuesday he was "surprised" by the discovery of the files and was "co-operating" with the justice department's review.

The controversy comes as the Democratic president faces scrutiny from a new Republican majority in the US House of Representatives.

"Now that Democrats no longer have one-party rule in Washington, oversight and accountability are coming," James Comer, the new chairman of the House Oversight Committee, said on Wednesday.

The committee is launching inquiries into the president and his family, including a request for the White House to turn over documents and communications related to the classified files.

The law requires that all White House records, including classified ones, be turned over to the US National Archives, after an administration's time in office.

Last August, FBI agents searched the Florida home of Mr Biden's predecessor and seized more than 10,000 files that Mr Trump had failed to turn over to the National Archives.

The justice department had issued a subpoena for the return of the classified files before the FBI showed up at Mar-a-Lago.

More than 300 documents with classified markings, including 18 marked top secret, were recovered by federal agents from the golf club in Palm Beach.

The White House has said Mr Biden's lawyers alerted the National Archives as soon as they recovered the classified materials at the think tank, and the agency retrieved the materials the next morning.
