While President Donald Trump and first daughter Ivanka Trump were attending Treasury Secretary Steve Mnuchin's wedding over the weekend, Donald Trump Jr. and his family appeared to be having a great time on a Caribbean vacation.

The first son, his wife Vanessa and their children went scuba diving and fishing during their getaway to the Bahamas.

Trump posted a photo of his wife and his three youngest children -- 5-year-old Tristan, 4-year-old Spencer and 3-year-old Chloe. His two older children, 10-year-old Kai and 8-year-old Donald III, were not featured in any of his Instagram photos from this year's trip.
