As has become common over the past few years, President Joe Biden has once again abandoned the White House and Oval Office for a week-long vacation with members of his family.

In what should be his final vacation as the president, Biden was spotted arriving on Thursday on St. Croix of the U.S. Virgin Islands in the Caribbean, according to the island territory's Daily News.

It is expected that Biden, who has been dubbed "Crucian Joe" by locals because of the frequency of his near-annual post-Christmas getaway to the tropical island, will stay there and not return to Washington D.C. until at least after the New Year begins.

Biden absent from the White House once again

The Hill reported that President Biden has been sharply criticized in prior years for his family vacations to St. Croix due to the optics of his slipping away from the White House while there are ongoing crises and work to be done on various domestic and foreign issues.

Of course, given the lame-duck status of his nearly concluded presidency, it isn't clear that he would be doing anything worthwhile if Biden had remained in D.C. instead of going on vacation.

To be sure, Biden did sign into law 50 bills passed by Congress earlier in the year on Christmas Eve, but that brief flurry of activity -- not to mention his recent highly controversial pardons and commutations -- amount to little following his veritable disappearance during the crisis negotiations a week earlier over a spending bill to avoid a possible partial government shutdown.

The Hill also noted that while the trip to St. Croix will likely be Biden's final vacation, it won't be his last trip away from the White House before his term expires in a little more than three weeks.

Though the dates of travel remain unclear, Biden is tentatively scheduled to visit Italy at some point next month to meet with the Catholic pope and Italian government leaders.

Where Biden is staying could be a problem

According to the New York Post, there is another potential controversy brewing related to President Biden's vacation to St. Croix that revolves around where he and his family will stay while there and whether or not they will pay fair market rates for the lodging.

As they have done in years past, the Biden family will stay at a luxury beachfront villa owned by billionaire business owners and Democratic donors Bill and Connie Neville -- a property that is typically listed for rent on VRBO for around $900 per night.

If the Bidens aren't paying to stay at the Nevilles' beachside vacation property, their lodging could be considered a "gift" that should be disclosed on annual ethics forms -- a disclosure that Biden has critically not made in the past.

The failure to make such required disclosures could go beyond a mere ethics violation and instead constitute a federal crime punishable by up to five years in prison, in that 18 U.S.C. § 1001 prohibits anyone under the U.S. government's jurisdiction from "knowingly and willfully" making any "materially false, fictitious, or fraudulent statement or representation; or ... any false writing or document knowing the same to contain any materially false, fictitious, or fraudulent statement or entry."

More evidence of the Biden family's "grift and corruption"

The former White House budget office's top attorney, Mark Paoletta, who is set to reprise that same role in President-elect Donald Trump's imminent second term, previously called out President Biden for his tendency to not disclose that his family stays rent-free at the homes and vacation properties of wealth friends and donors.

In a statement to the Post in May, Paoletta said, "His habit of taking over donors’ homes for vacations and not paying nor disclosing is consistent with his family’s long history of grift and corruption."
