Presidential nominees Hillary Clinton and Donald Trump are not expected to attend the 15th annual commemoration of the 9/11 terror attacks Sunday in lower Manhattan.

The Democratic former secretary of state and the Republican real estate magnate have not confirmed to the National September 11 Memorial & Museum that they will participate in the ceremony, organization spokesman Michael Frazier said Tuesday.

President Barack Obama also has not indicated he will attend, Frazier said.

“We have not gotten any confirmation from them,” Frazier said, adding that accommodations could be made if they changed their minds.

Clinton and Trump have said they will suspend campaign events on the day of the anniversary, as the city and nation remember the nearly 3,000 lives lost in the attacks.

Trump spokeswoman Hope Hicks confirmed he will not be at the 9/11 ceremony. She did not say what his schedule will entail.

A Clinton aide said the candidate’s plans for Sunday will be made public at a later time.

Both Clinton and Trump have ties to New York. Clinton was New York’s senator at the time of the attacks, while Trump was raised in Queens and resides in Manhattan.

Mayor Bill de Blasio, a Democrat, and former Mayor Rudy Giuliani, a Republican and mayor at the time of the attacks, are to be among the attendees at Sunday’s ceremony.

In 2012, when Obama was vying for re-election against Mitt Romney, neither was at the World Trade Center on Sept 11. The president attended a memorial service at the Pentagon, and the then-GOP nominee addressed the National Guard Association convention in Reno, Nevada.

In the 2008 presidential election cycle, however, Obama and Sen. John McCain (R-Arizona) both visited Ground Zero on the anniversary of the attacks.
