The president and his family relaxed under a sun lounger, under the watchful eye of their Secret Service detail.
But other beachgoers seemed to pay the presidential entourage little notice, and continued to enjoy the sunny day.
Finnegan’s father, Hunter Biden, 52, was not with the group. Joe and Jill paid $2.74 million for their beachfront home in Rehoboth Beach in 2017.
It comes as the Biden administration continues to refuse to address the scandal of cocaine being found in the White House as well as Hunter’s lovechild.

When the Bidens bought the Delaware mansion, Joe said in a statement that it was the culmination of a lifelong dream.
His main residence throughout his life has been in Wilmington, Delaware, 100 miles away.
‘Throughout our careers, Jill and I have dreamed of being able to buy a place at the beach at home where we can bring the whole family,’ said Biden, who was 74 when he bought it.
‘We feel very lucky that we’re now able to make that happen and are looking forward to spending time with our family.’
The beach house has six bedrooms and various outdoor and indoor entertainment spaces, with large west- and east-facing porches overlooking the Atlantic.
It also boasts a backyard patio and grill station, and a large dining room open to the kitchen, photos from a former listing show.

The Bidens have seven grandchildren. The president’s son Hunter Biden shares daughters Naomi, 29, Finnegan, 22, and Maisy, 21, with ex-wife Kathleen Buhle, and son Beau Jr., 2, with his current wife, Melissa Cohen. He also fathered a child in 2018. Biden’s eldest son, the late Beau Biden, welcomed daughter Natalie, 18, and son Robert ‘Hunter,’ 16, with wife Hallie.

The First Family were enjoying the beach as the Secret Service continues its investigation into who brought a bag of cocaine into the White House last week.
The dime-sized bag was discovered on Sunday, while the president and his recovering cocaine-addict son Hunter were at Camp David for the weekend.
The Secret Service are carrying out DNA and fingerprint analysis to try and find out who brought it to the White House grounds.
On Thursday, it was revealed the bag of powder was found near the White House’s West Executive entrance, not the West Wing lobby, as previously stated.
That entrance – which is in the West Wing but on the floor below the lobby – is also a heavily trafficked area, a description White House officials have used as a way to explain their doubts the culprit will be found.
On Friday, White House press secretary Karine Jean-Pierre refused to say whether the Biden family had been officially ruled out, but would not give any details on the investigation.
‘You know, there has been some irresponsible reporting about the family and so I’ve got to call that out here,’ the press secretary said. ‘And I have been very clear.’
The Bidens were at Camp David at the time the cocaine was found. They are seen on July 4, having returned after their weekend away
Senator Ted Cruz on Friday said he did not believe that any of the Biden family were involved in bringing cocaine to the White House, but accused the administration of a cover up

Senator Ted Cruz on Friday accused the White House of a ‘cover up’, which he said was ‘astonishing’.
‘You know, my guess is it probably isn’t Hunter’s,’ said Cruz, speaking on Friday’s episode of his podcast, Verdict.
‘I don’t know that, obviously. We know that Hunter has a drug problem. We know that he has used cocaine and use crack cocaine in the past.
‘But I doubt Hunter Biden is going in the West Wing all that often and going in that entrance all that often.’
The Texas senator speculated that a ‘senior Biden official’ was responsible.
‘I think it is in all likelihood someone who works in the Biden administration, some senior Biden official, which makes the cover-up all that the more astonishing,’ he continued.
He said he was surprised that the Secret Service had not yet found who was responsible.
‘That’s insane,’ he said. ‘And the only reason they would put out a statement saying we will never know who it was, is the same reason why the DOJ and the FBI is engaged in a cover-up of Hunter Biden’s acts of criminality, of Joe Biden’s acts of criminality.
‘Sadly, this administration is more than willing to politicize, look, it would be embarrassing if we discover that a senior White House aide is bringing cocaine into the west wing to do schedule-one, serious drugs in the White House.
‘And so their answer instead is, of course, we’re not going to prosecute it. We’re not going to investigate it. And you know what, we’ll just never know who did it.’
