PALM BEACH, Fla. — President Trump’s South Florida estate is no longer just the place where he goes to escape.

He has described the sprawling Mar-a-Lago property as the Winter White House and has spent two weekends there so far this month.

But it’s also become a magnet for anti-Trump protesters and the subject of an ethics debate over his invitation to Japanese Prime Minister Shinzo Abe to join him this weekend, even though Trump has pledged to pay for the accommodations.

Demonstrators plan to assemble Sunday near the estate to protest Trump’s decision on the Dakota Access oil pipeline.

The North Dakota project, opposed by a Native American tribe fearful of water contamination from potential oil leaks, had stalled in Democrat Barack Obama’s administration. Trump’s executive order cleared the way for the developer to start building the final stretch of pipeline.

During Trump’s other weekend in Florida, several thousand people marched near the property to protest his temporary ban on travel to the United states by refugees as well as citizens of seven mostly Muslim countries. A federal appeals court has upheld a lower court’s decision that temporarily blocks the ban’s enforcement.

Trump’s election is also putting charitable organizations, such as the American Red Cross, in an awkward position for choosing Mar-a-Lago for events booked months in advance. The Red Cross held its annual fund-raiser there Feb. 4, about a week after Trump issued the travel ban.

After meeting at the White House on Friday, Trump, Abe, and their wives headed straight to Mar-a-Lago, where they enjoyed a late dinner at the crowded patio restaurant.

Joining them were New England Patriots owner Robert Kraft, and several interpreters. Paying members and their guests mingled with Trump and Abe into the night.

On Saturday, Trump and Abe went to Trump’s golf course in Jupiter and were expected to hold more talks at Trump’s various Florida properties.

World leaders typically exchange gifts, and Trump and Abe did so when Abe rushed to New York City in November to become the first foreign leader to meet with Trump after the election.

White House spokesman Sean Spicer said Abe’s free-of-charge stay at Mar-a-Lago is Trump’s gift to Abe this time around. But the gesture wasn’t sitting well with government watchdog groups.

Robert Weissman, president of Public Citizen, said Trump and Abe don’t need to meet at Trump’s commercial property, where the membership fee is $200,000.

‘‘Hosting a foreign leader at the president’s business resort creates impossible sets of conflicts,’’ he said. ‘‘If the president hadn’t offered to pay, the US government would be paying Donald Trump’s business for the purpose of hosting the Japanese leader.’’ Typically, the US government would pick up the costs of such a visit.
