WASHINGTON – Disgraced first son Hunter Biden lived off and on at the Delaware home where classified documents from Joe Biden’s time as vice president were found last month — giving him unrestricted access to America’s secrets while he was addicted to drugs, hammering out shady foreign business deals and under federal investigation.

The now-52-year-old began listing the Wilmington home as his address following his 2017 divorce from ex-wife Kathleen Buhle — even falsely claiming he owned the property on a July 2018 background check form as part of a rental application.

Hunter also listed the home as the billing address for his personal credit card and Apple account in 2018 and 2019, respectively, Fox News Digital reported Friday after reviewing emails from his abandoned laptop.

During the same period, the now-first son was in the grip of a crack cocaine addiction costing thousands of dollars. At one point in August 2018, Hunter was recorded begging his sister-in-law-turned-lover, Hallie Biden, to let him use his credit card points to pay for a stay in rehab.

Another former girlfriend of Hunter’s, Zoe Kestan, testified to a federal grand jury in February of last year that the couple stayed for a month in 2018 at the notorious Chateau Marmont hotel in Los Angeles, where — the younger Biden wrote in his 2021 memoir — he “learned how to cook crack” before being “blacklisted” from the property over complaints tied to his drug use.

Hunter also frequented prostitutes during this time, dropping more than $30,000 on sex workers between November 2018 and March 2019 alone — making him a possible target for blackmail.

On Thursday, President Biden confirmed that sensitive papers had been found in the locked garage of the home, where he also keeps his vintage 1967 Corvette Stingray.

“My Corvette is in a locked garage, OK? So it’s not like they’re sitting out on the street,” the defensive president told reporters when asked about the discovery.

On Monday, the White House disclosed an initial batch of classified documents had been uncovered on Nov. 2 by the president’s personal lawyers while clearing Biden’s former office at the Penn Biden Center for Diplomacy and Global Engagement in Washington.

It’s unclear whether the documents found in Wilmington on Dec. 20 were shipped directly to Biden’s home upon his leaving the vice presidency in January 2017 or if they were initially stored elsewhere rather than given to the National Archives as required by federal law.
