David Marcus writes for DailyMail.com about the president’s latest offenses.

Renowned artist, international playboy, scallywag and presidential scion, Hunter Biden is prancing around the Emerald Isle with his dear old dad, all the while under Justice Department and congressional investigations.

Must be nice. But back at home, Americans have a few questions.

In fact, millions have been waiting years to resolve the myriad probes and scandals swarming around the troubled second son of the president. And instead, they get slapped in the face with this?

The Biden Family European Vacation.

Not since the Griswold’s have we witnessed such a disaster.

And it’s shameless.

It might be one thing if the recovering crack addict of sordid laptop fame was just quietly tucked into the back of Air Force One, keeping a low profile while visiting with Joe’s distant cousins. But no. He is openly assisting his dad at official events.

Don’t forget!

Hunter is currently under federal investigation for failure to pay taxes linked to his shady international business dealing. He’s also being investigated by House Republicans for allegedly leveraging the political power of his famous father to help him sell access to the highest levels of the American government.

In 2013, Hunter tagged along in Air Force Two, with then-Vice President Joe Biden, on an official visit to Beijing. Little did we know at the time, but Hunter was actually using the trip to court Chinese investors, who ended up paying him to help promote their interests in the West.

Ye Jianming, the former chairman of Chinese energy conglomerate CEFC, once gave Hunter Biden a 3-carat diamond estimated to be worth $80,000.

Last month, House Republicans revealed that another firm, linked to CEFC, wired $3million to a Hunter’s business partner. And, according to investigators, that money was then doled out to members of the Biden family, including Joe’s daughter-in-law, Hallie and his brother, James.

What was Hunter paid to do? That’s still unclear. But I bet it wasn’t for nothing.
