BEDMINSTER — President Donald Trump kept up a tradition while spending the weekend at his golf club on Saturday as protesters plan to drive a motorcade past his golf club prior to a fundraiser for congressman Tom MacArthur Sunday afternoon.

The president popped in on the wedding of Laura Pitakowski on Saturday night, according to her Instagram account, and posed for pictures with the new bride and her husband Matthew as first reported by the news website The Hill.

"When POTUS shows up at your to say #gladhillbemine was one for the books," Pitkowski wrote with her post. The picture was remobed  from her account on Sunday afternoon.

A second photo showed Trump standing at the reception as guests watched.

Wedding guest Sean Burke told the Washington Post the president's visit was very brief. He hugged the bride, posted for pictures and signed red "Make America Great" baseball caps that other guests had brought. Burke said it appeared to be a complete surprise to all and very impromptu.

The Post also reported Trump appeared on Friday night for the Far Hills Country Day School eighth graduation dinner.

An old brochure for the club that said Trump often stops by weddings at the club if his schedule allows, according to the New York Times.

Trump is spending his second weekend as president at the "Summer White House," and hosts a fundraiser for New Jersey congressman Tom MacArthur on Sunday afternoon before heading back to Washington. It's the first political fundraiser Trump has hosted for a member of Congress.

Several groups that have dogged MacArthur over his role in crafting a healthcare bill that addressed concerns about pre-existing conditions plan a motorcade drive by Trump's club before the event starts at 4 p.m.

Analilia Mejia of NJ Working Families told the Townsquare News Network the "People's Motorcades" have been going on for about a month and called it "one part protest and one part parade."

She said many of MacArthur's constituents from the third Congressional district that spans the length of the state from Camden County to Ocean County are among the over 100 people who have committed to participate in Sunday's motorcade.

"We're all outraged that he is going the extra mile to essentially take away healtcare from millions of Americans, many of which have pre-existing conditions," Mejia siad.

MacArthur said his amendment protects pre-existing conditions, a sticking point among many lawmakers. Many conservatives were won over by the amendment, which creates an $8 billion pool of money to help people with pre-existing medical conditions afford coverage. The change to the law would allow insurers to raise premium prices for people with such pre-existing conditions.
