Trump will explain tariffs on electronics on Monday

Toy stores are among the hardest hit by President Donald Trump's escalating trade war with China as 77% of toys sold in the United States are made in China, according to the Toy Association.

Amy Rutherford, the owner of Pippin Toy Co. in Alexandria, Virginia, told ABC News that virtually everything in her store is made in China. Even the toys that are branded as "Made in USA" are actually made with parts from China.

The price of a stuffed panda sold at her store will rise from $32 to $80 because of the 145% tariff on Chinese products, she said.

"If it's at an $80 panda from $32, then that makes a big difference. People aren't going to want to pay that," she warned.

"I'll be able to absorb some of it, but I certainly can't absorb 145%. That's not possible. Not even half of that is possible," Rutherford added.

She said there are not enough toys made in America to fill her store with the variety she's currently selling.

Rutherford said she is trying to conserve her store's budget but added that she is concerned she may have to lay off workers in the future.

During Friday's press briefing, the White House refused to explain President Donald Trump's optimism that he can cut a deal with China on tariffs despite ABC News' Mary Bruce pressing Karoline Leavitt multiple times about the negotiations -- or lack thereof.

"The President, as I said from the podium, just a few days ago when I was up here, would be gracious, if China intends to make a deal with the United States," Leavitt said. "If China continues to retaliate, it's not good for China and the United States of America is the strongest, best economy in the world, as evidenced by the more than 75 countries who have called the administration immediately to cut good deals."

When pressed again on what is making Trump optimistic, Leavitt sidestepped, only saying "he's optimistic," without explanation.

ABC News's Mary Bruce asked White House press secretary Karoline Leavitt about the tariff situation with China and why President Donald Trump hasn't picked up the phone and negotiated directly.

Leavitt declined to respond.

"I will leave it to that, our national security team to get these discussions underway," she said.

In a new post on his media platform, President Donald Trump said that the U.S. is "doing really well on our TARIFF POLICY."

"Very exciting for America, and the World!!! It is moving along quickly," Trump said in Friday's post.
