The pair have vacationed at Kiawah Island several times, including in 2009 and 2013, as well as more recently when they spent a weekend there in June with the family of Beau Biden, the vice president's late son.
Chatter about Biden potentially launching a presidential bid to challenge Hillary Clinton, the Democratic frontrunner, escalated this week ahead of his visit to the sea island spot near Charleston. 
Reports last weekend that Biden was taking meetings about a possible run spurred speculation he might launch a surprise Democratic challenge. The race currently has five candidates, but Clinton remains the frontrunner, followed by Sen. Bernie Sanders (I-Vt.), based on recent polls.
Biden joked about the possibility earlier in the week when asked by a reporter, but has offered no signals about what he might do. He is expected to make a final decision by September.
