President Donald Trump, aboard Air Force One on Sunday night en route back to Washington, D.C., after a weekend in Florida, said there "shouldn't be ambiguity" amid his administration's repeated about-faces on tariffs.

He said semiconductor tariffs “will be in place in the not distant future” and that he would announce at what rate “over the next week.”

The president said on Saturday he would announce specifics on Monday.

Trump, when asked if he would declare tariffs on iPhones and tablets, said, "That’s going to be announced very soon" but that the administration is going to with companies about it because “you have to show a certain flexibility.”

China says the Trump administration’s exemptions for smartphones, laptops and other electronics is a “small step” in correcting a “wrong practice,” urging the U.S. to completely cancel Trump’s reciprocal tariffs.

"We urge the US … to take a big step to correct its mistakes, completely cancel the wrong practice of 'reciprocal tariffs' and return to the right path of mutual respect," China's Commerce Ministry said in a statement.

Beijing is now “evaluating the impact” of the exemption, the statement said.

Hedge fund billionaire and vocal Trump supporter Bill Ackman posted on X today: “The rift is healing. China ‘asks’ for relief from the tariffs creating an opening for a 90-day China tariff pause and negotiations.” Ackman had earlier in the week urged Trump to pause those reciprocal tariffs shortly before the president announced the pause, warning that businesses would go bankrupt.

But on Sunday afternoon, Trump posted on Truth Social that tariffs on these products are “just moving to a different Tariff ‘bucket.’”

“NOBODY is getting ‘off the hook’ for the unfair Trade Balances,” the president added. “Especially not China, which, by far, treats us the worst!”

Trump on Sunday said, “There was no Tariff ‘exemption’ announced on Friday" and that semiconductor tariffs will “just be moving to a different Tariff ‘bucket.’”

“NOBODY is getting ‘off the hook’ for the unfair Trade Balances, and Non Monetary Tariff Barriers, that other Countries have used against us, especially not China which, by far, treats us the worst!” Trump posted on his Truth Social platform.

Trump’s top economic and trade aides made the same argument on Sunday talk shows: that smartphones, computers and other electronics were removed from the sweeping reciprocal tariffs the president announced on April 2 and will be part of a separate national security classification under Section 232 of the Trade Expansion Act of 1962 Trump is to announce, they said.

“We are taking a look at Semiconductors and the WHOLE ELECTRONICS SUPPLY CHAIN in the upcoming National Security Tariff Investigations,” Trump wrote.

A bulletin posted by U.S. Customs and Border Protection late Friday night said the administration was exempting smartphones, computers, and other electronics from his reciprocal tariffs.

Trump did not push back Saturday night when a reporter asked for details on “exemptions.”

“I'll give you that answer on Monday. We’ll be very specific on Monday,” Trump said. “We're taking in a lot of money. As a country, we’re taking in a lot of money.”

President Donald Trump said he'll share more details on Monday on his plan for separate tariffs on semiconductor chips.

Asked about the plan by reporters aboard Air Force One on Saturday, Trump said, "We’ll be very specific on Monday. We're taking in a lot of money. As a country, we’re taking in a lot of money."

The comments came after the Trump administration announced that smartphones, computers, chips and other electronics would be exempt from the escalating tariffs Trump has imposed on other Chinese imports, which now stand at 145%.

House Minority Leader Hakeem Jeffries stressed Democrats will continue to “push back” in a bipartisan way to fight Trump's tariffs.

“The Constitution is very clear that tariffs and tax policy, the ability to raise revenue, that authority is vested in the Congress for a reason,” Jeffries said. “The Congress is most closely associated, particularly the House, with the American people.”

Jeffries said Congress has to start acting like a separate and co-equal branch of government. He decried Republicans for conceding to Trump and said the cost of living in America has gotten “too expensive” under the Trump administration.

“What we have witnessed under complete Republican control of government is a willingness to simply bend the knee to Donald Trump, no matter how much pain he is inflicting on the American people or how much damage Trump is doing to the American way of life,” he said.

Jeffries also slammed the president for harming American families and causing an “economic disaster.”

“This is a reckless economic sledgehammer that Donald Trump and compliant Republicans in the Congress are taking to the economy, and the American people are being hurt. Enough.”

Ahead of United States Trade Representative Jamieson Greer’s appearance on Capitol Hill, the leader said he hopes Greer can confirm if the president’s tariffs are an intentional scheme to enrich the wealthy.

“The Trump tariffs, which are a tax on the American people, are so reckless, so unstrategic, so lacking in any sophistication, that the only conclusion that one can draw is that Donald Trump and Republicans are intentionally tanking the economy,” he said. “Is it because, as Donald Trump has indicated, that during tough economic times, the rich get richer, and it's a buying opportunity?” he asked.
