The U.S. Secret Service has reportedly been paying large sums of money in order to protect President Joe Biden’s son Hunter Biden at his Malibu, California, home. This news comes at a time of heightened scrutiny regarding Hunter’s business dealings.

On Monday, ABC News reported that the Secret Service is spending about $30,000 a month on rent at a Malibu property to protect Hunter, 52.

It is standard practice for the Secret Service to provide protection to the president’s family wherever they might be located. As is the case for Hunter, this sometimes leads to controversial amounts of money being spent in order to do so.

During the Trump administration, the Secret Service reportedly was charged for its stays at properties owned by former President Donald Trump’s where he would frequently pay visits. In one case, the agency spent a purported $250,000 to protect Trump’s adult sons as they traveled overseas for business trips. These arrangements, while technically customary, were subject to criticism by Democrats in Congress who saw them as moves by Trump to enrich himself.

Like the case of the Trumps, Hunter’s protection costs seem to track with the wealthy, though controversial, lifestyle he has enjoyed from his years as a business lobbyist and a lawyer.

Last July, the New York Post identified the mansion Hunter resided at in Malibu as a $20,000 a month home where he resides with his wife and son. The outlet, citing listings for the home they identified, said the home is a 3,000-square-foot, four-bedroom, two-bathroom home with an open floor plan, solid oak floors, and 180-degree ocean views.

Hunter currently remains under a tax investigation by federal prosecutors in Delaware. Last week, the Wall Street Journal reported that federal prosecutors are seeking additional information from the president’s son and testimony to put before a grand jury.
