BEDMINSTER -- Less than a mile from one of GOP presidential nominee Donald Trump's golf course, Philadelphia artist David Gleeson climbed a ladder to the top of a big blue bus once used by Trump on the campaign trail, put down a golf ball with Trump's likeness on it, stretched and swung.
Gleeson and Brooklyn-based artist Mary Mihelic, whose bus was denied entrance onto the Trump National Golf Course on Wednesday, are among a growing number, including ranking Republicans, who are trying to knock Trump out of a presidential race. Gleeson has challenged Trump to a $180,000 golf duel.
Gleeson said he and Mihelic, members of an anti-Trump performance art group, have traveled to 42 states on the bus, stopping at various Trump rallies and random locations, delivering their message.

"It's called Driving out the Donald," said Gleeson, moments after hitting his tee shot into a wooded area off Lamington Road.
A phone call to Trump's New Jersey headquarters seeking comment wasn't returned.
On Wednesday, more women came forward publicly accusing Trump of inappropriate behavior toward them in the wake of a conversation with a television host in 2005 that was caught on a hot mike. During the conversation - described by Trump as "locker room talk" - he is heard boasting about kissing women without invitation and touching their private parts.
Gleeson and Mihelic have transformed the bus into a mobile art exhibit protesting Trump's candidacy. After leaving Bedminster, the bus was scheduled for stops at Trump's golf courses in Colts Neck and Pine Hill, said Gleeson.
