Photos of the US President at the wedding quickly took over social media
According to the CNN, members of the Secret Service came into the room minutes before Mr Trump was to enter in order to clear the way and make sure that guests didn't surround him.

Sean Burke, a guest at that wedding, told The Washington Post that Mr Trump's appearance was brief but got everyone excited. "It was very brief. He waved to everyone. Everyone obviously got very excited, got out of their chairs and came to take pictures," Mr Burke said. "The bride came running out, and he gave her a big hug and a kiss, so she was just ecstatic. And then the groom found out, too. ... No one knew it was going to happen."
This is not the first time that the 45th President of the US has crashed a wedding. In February this year, Mr Trump dropped in at Vanessa Falk's wedding reception at his golf retreat in Mar-a-Lago.
