When Donald Trump takes the presidential oath of office this January, wife Melania and youngest son Barron will not move to D.C., at least not immediately.

As first reported by the New York Post, the two will remain at the Trump Tower in Manhattan so that the 10-year-old first son can finish the year at his Upper West Side private school.

The Post quoted a source it called “close to Trump’s transition team” who said that “Melania is extremely close to Barron, and they have become closer during the campaign. The campaign has been difficult for Barron, and she is really hoping to keep disruption to a minimum.”

Barron is the only Trump child who is a minor—the other four have played active roles in their father’s presidential campaign. The eldest three are also executives at the Trump Organization and members of their dad’s transition team, raising serious concerns about conflicts of interest.

It was an open question at first whether President-elect Trump would move full time to D.C.,
though he confirmed that he would, adding that Melania and Barron will move to the White House “very soon. Right after he finishes school,” per CNN.

“No official statement has been released by the Trump family regarding transition timing, but like any parents they are concerned about pulling their 10-year-old son out of school in the middle of the year,” said transition spokesperson Jason Miller.

The Obama daughters Sasha and Malia both switched schools mid-year, attending Sidwell Friends. They are remaining in D.C. until Sasha finishes high school. The previous school-aged child in the White House, Chelsea Clinton, also attended Sidwell.

The Trumps haven’t given any indication they’ve decided on—or looked at—a D.C.-based school for Barron yet.

It’ll be the first time that a first lady won’t be living in the White House, according to the Washington Post, which noted exceptions like Martha Washington, who didn’t live there with her husband George because the house had not yet been built, or Anna Harrison, whose husband William Henry Harrison died a month after inauguration and before she could move in.

The decision has serious implications for New York City, where traffic around Trump Tower due to increased security and protests.

New York City Mayor Bill de Blasio called the heightened security measures “an unprecedented challenge.” He suggested to drivers that “to the extent that you can avoid the immediate area around Trump Tower, that will make your life easier and everyone else’s life easier.”

Restaurateur David Chang, who owns three restaurants near Trump Tower, tweeted that the security checkpoints were killing foot traffic and hurting local businesses.

The Secret Service said in a statement that it was taking into consideration the impact of its work on local residents and merchants in New York.

“As a matter of practice, security plans will evolve in order to address emerging threats and to improve efficiencies in its operations,” the statement says. “Whenever possible, the Secret Service will communicate these changes to community members without compromising operational security.”

Protecting the Trump family is costing New York City upwards of $1 million per day, reports CNN.
