The couple has a connection to the Trump National Golf Club in Bedminster. They were engaged at the property in 2017, NJ.com reported and held the reception there this year.
Nicole Perosi Mongelli and PJ Mongelli had also dressed up like an American flag and the president for Halloween, NJ.com reported.
The reception was decorated with Trump 2020 signs and American flags, NJ.com reported. They also gave guests Trump "gold" bars that were made of chocolate.
At first, the president greeted the bride and groom, where the bride told him "We love you so much," NJ.com reported.
A guest told him, "You have all supporters here. You're a class act that you came in here," according to NJ.com.
He then went to another part of the reception where he was greeted by chants of "USA."
This isn't the first time Trump attended a wedding held at one of his properties while in office. In 2017, he and Japanese Prime Minister Shinzo Abe visited a reception held at Mar-a-Lago in Palm Beach, Florida, CNN reported.
