The Army will rely on unused federal office space, including at the Department of Agriculture and the General Services Administration, to house an estimated 6,600 soldiers coming to Washington, D.C., on June 14 for its 250th birthday celebration.

Army officials told ABC News the soldiers will be sleeping on Army-issued cots inside empty federal office buildings.

The Army is also considering putting up some soldiers in buildings near Arlington National Cemetery and at Joint Base Myer-Henderson Hall in Arlington, Virginia.

"This will not displace any federal workers," Army spokeswoman Heather J. Hagan said.

Soldiers from every Army division were expected to begin arriving in the Capital on June 12, although Hagan said arrivals and departures would depend upon each individual unit.

President Donald Trump was asked on Friday what parameters he's given Treasury Secretary Scott Bessent as he meets with Chinese officials on trade in Switzerland this weekend.

"We have to make a great deal for America," Trump said.

Pressed if he'll be "disappointed" if a deal isn't reached, Trump said no but expressed optimism on the upcoming talks: "I think we're going to come back with a fair deal for both China and us."

Asked if he's given Bessent a "number of how low you're willing to go," Trump said he has but wouldn't give details.

"I put out a number today -- 80% -- so we'll see how that all works out," the president said.

President Donald Trump said on Friday he wants to maintain a minimum 10% baseline tariff against trade partners, even after deals are made.

"Does that mean that countries offering zero tariffs won't get reciprocity?" a reporter asked.

"You are always going to have a baseline," Trump said. "I mean, there could be an exception at some point, we'll see. You know, somebody does something exceptional for us, that's always possible. "But basically you have a baseline of a minimum of 10%. And some of them will be much higher 40%, 50%, 60%, as they've been doing to us over the years."

With the first flights of white Afrikaner South Africans set to arrive as early next week, the White House was pressed on why bringing them to the U.S. as refugees is a priority for the administration -- as it is cracking down on other kinds of immigration.

"This group in South Africa has faced racial persecution," White House press secretary Karoline Leavitt said in Friday's press briefing. She went on to claim their farmland is being taken away, though the law passed by South Africa earlier this year does not allow land to be expropriated without an agreement with the owner.

White House deputy chief of staff Stephen Miller called it a "really exciting news story" as he argued President Donald Trump is returning to the refugee program's intention of providing a safe solution for individuals forced to leave their country due to conflict and not a "solution for global poverty."

"What's happening in South Africa fits the textbook definition of what refugee program was created. This is persecution based on a protected characteristic, in this case, race," he said.

Miller said next week's flight is "just the beginning of what's going to be a much larger-scale effort. And so those numbers are going to increase."
