Four unanswered questions about the Biden documents

In total, roughly 20 classified files were recovered between the two locations, reports CBS, citing a federal law enforcement official familiar with the investigation. The papers only began to come to light in news reports last Monday, but the first batch was found at Mr Biden's former institute, the Penn Biden Center in Washington DC, back in November. That was days before the midterm elections, which saw Republicans narrowly win control of the US House of Representatives.

OneThursday it emerged that a second cache of files had been found on 20 December by Biden aides in a garage and adjacent room at his private home in Wilmington, Delaware. On Friday, as he hosted Japanese Prime Minister Fumio Kishida at the White House, Mr Biden ignored questions from journalists about the growing controversy. A day earlier, Mr Biden - who has previously described his predecessor Donald Trump's alleged mishandling of classified material as "totally irresponsible" - told reporters the documents were found locked in a garage next to his 1960s Chevrolet Corvette sports car.

Who is the special counsel in the Biden probe?

Earlier on Friday, House Oversight Committee Chairman James Comer wrote to the White House asking whether the president's scandal-plagued son, Hunter Biden, had access to files at the president's Wilmington residence. Republicans are also calling on the White House to release visitor logs of Mr Biden's homes, but the White House has refused to say if such information will be divulged. During his time in office, Mr Biden has spent nearly 200 days - or more than a fourth of his presidency - in his home state of Delaware, according to an Associated Press tally, including a stay in Wilmington this weekend.

Mr Trump is also under investigation by the justice department after he kept more than 300 classified files - including some marked with secret and top secret designations - at his Mar-a-Lago estate in Florida, some of which were seized by FBI agents executing a search warrant last August.
