BEDMINSTER -- More than 100 people spent about two hours Sunday afternoon driving by President Donald Trump's private golf club in protest of his administration's stance on numerous issues, including healthcare, immigration and the environment.

The activists gathered at Ten Eyck Park in Branchburg and the Clarence Dillon Public Library in Bedminster to decorate their vehicles with signs before driving by Trump National Golf Club, where the president has been staying since he arrived in the Garden State on Friday afternoon.

"We want Donald Trump to know he is not welcomed in New Jersey," Craig Garcia, political director at the New Jersey Working Families Alliance, said as he handed out plastic horns to people driving in the line of vehicles.

Garcia said people from numerous organizations have participated in similar motorcades every weekend since Trump first visited the golf club as president in May.

Bennet Zurofsky, one of two attorneys who attended the event to represent drivers if they got in legal trouble, said the purpose of the motorcade Sunday was to disrupt traffic heading into a fundraiser Trump was expected to host for Rep. Tom MacArthur (R-3rd Dist.).

MacArthur's amendment allowing states to opt out of health insurance protections -- including those for policyholders with pre-existing conditions -- paved the way for House Republicans to pass legislation repealing and replacing Obamacare.

The president embraced the bill, which the Congressional Budget Office said would leave 23 million fewer Americans with health insurance by 2026. MacArthur and other GOP lawmakers joined him at a Rose Garden celebration after it passed.

"This issue is very serious," Barbara Blonsky, of Mount Laurel, said of the millions of Americans who would be left without health insurance. "We need MacArthur voted out in 2018 because he doesn't listen to his constituents."

In response to the protest, MacArthur spokesman Chris Russell said the congressman listens to his constituents to make decisions he believes are best. Russell said MacArthur ran for Congress "to confront big problems and take tough stands, not decorate a chair."

"Obamacare is failing, premiums are rising and choices are dwindling," Russell said in an email. "Instead of allowing it to completely collapse, Rep. MacArthur took action to ensure people continued to have access to quality care, while reducing premiums for families and she'll business."

The White House did not immediately respond to a request for comment.

Earlier this month in advance of the fundraiser, MacArthur set up a special joint fundraising committee that will allow him to take in individual contributions of as much as $257,700, rather than the maximum $5,400 for his re-election committee, Federal Election Commission filings show.

Donors must have given at least $5,400 to attend the fundraiser Sunday, which the Associated Press reports netted more than $800,000.

Those who contributed or raised $100,000 for MacArthur were listed as hosts and got a chance to take a picture with the president. Couples who donated or raised $25,000 were co-hosts and also be able to pose with Trump, according to an invitation obtained by NJ Advance Media.

Besides MacArthur's re-election campaign, donations will go to his leadership political action committee, the New Jersey Republican Party and the National Republican Congressional Committee, the House Republicans' fundraising arm.

After the motorcade, the protesters held a "die-in" near the intersection of Lamington Road and U.S. Route 206, in which at least 30 people laid on the ground holding tombstones labeled with pre-existing conditions.

Jack Gavin, 57, of West Caldwell, could be seen handing out "Facts Matter" pins and an American Civil Liberties Union editions of the Constitution. He called on the administration to stop "playing fast and loose with the facts."

"This regime is the greatest tragedy I've seen in the 67 years of my life," Linda Portoghese Dalo, a lifelong Democrat who voted for Hillary Clinton but would have preferred Bernie Sanders, said as she held a sign about Russian interference in the 2016 election. "Nixon wasn't as bad as this."
