The final day of the U.S. Women's Open tournament had an even bigger stage with President Trump in attendance.
He's the first sitting president to attend the event, which took place Friday through Sunday at his Trump National Golf Club in Bedminster, N.J.
For hours each of the tournament's last three days, people who had bought tickets to the championship found themselves with front-row seats to Trump's glad-handing, chit-chatting, sports watching and french-fry eating.
Usually, Trump had his back to the green and the oglers, watching the competition on a TV screen when not greeting a stream of guests and visitors that included golfers and club managers plus his son, daughter-in-law and national security advisor.
Every so often, Trump acknowledged the crowd outside the booth, waving to them, pointing at those wearing Trump campaign merchandise, and offering a thumbs-up or a first bump.
Outside the course, a small procession of cars and trucks circled the course and bore signs criticizing Trump and supporting women's rights.
Protesters have criticized the U.S. Golf Assn., which operates the tournament, for not moving it to a different venue after audio surfaced last year of Trump making derogatory comments about women.
On Sunday, four protesters from the women's rights group UltraViolet entered the club with event tickets and positioned themselves in front of Trump's viewing booth wearing purple shirts that read "USGA: DUMP SEXIST TRUMP."
At times, Trump supporters taunted the protesters and criticized reporters for giving them attention. Others welcomed their presence. The protesters eventually left on their own accord.
Players competed for attention with the course's namesake. Again and again, club staff and volunteers asked the crowd gathered near Trump to hush so golfers like Lexi Thompson and Stacy Lewis could focus on their game.
Trump has spent nearly every weekend of his presidency visiting a Trump-owned property, golf course or hotel. Many critics and ethics experts have accused the president of using his position to enrich himself.
