Vacationing Trump greets wedding guests at his New Jersey golf club

Video captured the president chatting and taking selfies with guests.

"Everyone having a good time?" Trump, flashing a thumbs up, asked a group of guests as he posed for selfies, as seen in the video above.

After snapping selfies, the president -- wearing his signature "Make America Great Again" red baseball cap, then heads toward a golf cart.

Earlier on Saturday, Trump defended his time at Bedminster, tweeting, "Working in Bedminster, N.J., as long planned construction is being done at the White House. This is not a vacation -- meetings and calls!"
