Trump interrupts golf club break to tell voters he is not on holiday
Donald Trump may be spending time in the sand but he is making clear to US voters he is not on holiday.
The US president has repeatedly rejected the idea he is having a relaxing August getaway, posting on Twitter over the weekend: "This is not a vacation - meetings and calls!"
Mr Trump's staff has labelled the trip a "working vacation".
Aides say Mr Trump is meeting with aides and cabinet members to discuss policy and he is expected to go to New York City next week.
They have declined to answer repeated questions about whether he is playing golf.
Still, the only sighting of Mr Trump since he landed in New Jersey was a video that surfaced online on Saturday of the president greeting wedding guests at his club.
Dressed in a golf shirt and a red Make America Great Again hat, Mr Trump exited a golf cart to chat with the guests.
So far, the main proof Mr Trump is not relaxing is his steady flow of Twitter comments, particularly on Monday, when rain likely kept him indoors.
Throughout the day he pushed out messages backing his supporters, attacking Democratic Senator Richard Blumenthal and highlighting a vote by the United Nations Security Council to slap more sanctions on North Korea.
"Working hard from New Jersey while White House goes through long planned renovation," he said, referring to White House updates under way, including the replacement of a West Wing heating and cooling system.
Getting out of Washington in the summer is a well-established presidential tradition.
President George W. Bush enjoyed his Texas ranch, while President Barack Obama frequented Martha's Vineyard in Massachusetts.
President Ronald Reagan went out to Santa Barbara, California.
Of course, the president never really leaves the job, travelling with a mini-White House of advisers and aides and continuing briefings and conversations wherever he goes.
While there is precedent for Mr Trump to get a change of scenery, the president may be chafing at calling it a holiday because he frequently slammed his predecessor for leaving town and for playing golf.
In August 2011, Mr Trump tweeted: "@BarackObama played golf yesterday. Now he heads to a 10 day vacation in Martha's Vineyard. Nice work ethic."
"President Trump is hyper-sensitive about the word 'vacation' because he hammered President Obama for so long for taking it," said Douglas Brinkley, a presidential historian with the James A. Baker III Institute for Public Policy.
Mr Brinkley added that presidents are "always having to work. Hence the phrase 'working vacation'."
So far, Mr Trump has spent 13 of 28 weekends in office away from the White House, mostly at his properties in Palm Beach, Florida, or in Bedminster, New Jersey, according to an Associated Press count.
The figures include a weekend during official travel overseas, and Father's Day weekend at Camp David, the government-owned presidential retreat in Maryland.
Anita McBride, who served as Laura Bush's chief of staff, agreed that the White House travels with the president.
She said getting out of Washington has benefits, recalling President George W. Bush's love of cycling and other activities at his ranch in Crawford, Texas.
"That's where he recharged his batteries," she said.
"Any of us who have worked in the White House really understands the need for getting away."
The real world often intrudes on these summer presidential getaways.
In 1998, Bill Clinton briefly came back to Washington from Martha's Vineyard to deal with missile attacks in Sudan and Afghanistan.
Mr Reagan came home early from a California vacation in 1983 after Korean Airlines Flight 007 was shot down in by a Soviet fighter jet.
In 2005, George W. Bush was criticised for not cutting off his vacation after Hurricane Katrina hit New Orleans.
Mr Brinkley recalled a series of serious events that intruded on Mr Obama's summer breaks, including the beheading of journalist James Foley by Islamic State militants in 2014 and Syria's chemical weapons use in 2013.
"Things happen when presidents are away," said Mr Brinkley.
"Every August you have something horrific that's going to happen."
