Hunter Biden has joined meetings with President Joe Biden and his top aides since his father returned to the White House from Camp David, Maryland, on Monday evening, according to four people familiar with the matter.
The president’s son has also been talking to senior White House staff members, these people said.
While he is regularly at the White House residence and events, it is unusual for Hunter Biden to be in and around meetings his father is having with his team, these people said. They said the president’s aides were struck by his presence during their discussions.
A federal jury in Delaware found Hunter Biden guilty last month on gun-related charges. He remains under indictment accused of tax-related felonies, to which he has pleaded not guilty. Shortly after the jury found him guilty, he returned to his home in California.
One of the people familiar with the matter said Hunter Biden has been closely advising his father since the family gathered over the weekend at Camp David after Thursday’s debate. This person said Hunter Biden has "popped into" a couple of meetings and phone calls the president has had with some of his advisers.
