President Donald Trump on Monday continued to lash out at the Supreme Court, days after a majority of justices, including two of his conservative nominees, struck down most of his global tariffs as illegal.

In a series of social media posts on Monday, Trump wrote he had a “complete lack of respect” for the nation’s high court and that “they should be ashamed of themselves.”

“The supreme court (will be using lower case letters for a while based on a complete lack of respect!) of the United States accidentally and unwittingly gave me, as President of the United States, far more powers and strength than I had prior to their ridiculous, dumb, and very internationally divisive ruling,” Trump wrote.

“The court has also approved all other Tariffs, of which there are many, and they can all be used in a much more powerful and obnoxious way, with legal certainty, than the Tariffs as initially used,” Trump added.

Trump will face some of the Supreme Court justices in person on Tuesday night when he delivers his State of the Union address. Justices are typically seated in front of the president in the first few rows, though their attendance is voluntary and several have skipped the event in recent years.

The court’s 6-3 ruling on Friday, which marked a rare rebuke on his administration, deemed that the International Emergency Economic Powers Act (IEEPA) does not give Trump the power to unilaterally impose the sweeping tariffs he issued on most U.S. trade partners.

Trump has since sought to revive the tariffs, which were a longtime political goal of his and a centerpiece of his economic agenda in his second term.

Over the weekend, Trump announced he was imposing a 15% global tariff under a different legal authority: Section 122 of the Trade Act of 1974. But that authority is more limited, allowing the tariffs to last only for 150 days without congressional approval.

Trump’s repeatedly signaled he won’t seek additional action from Congress on tariffs.

“As President, I do not have to go back to Congress to get approval of Tariffs. It has already been gotten, in many forms, a long time ago!” Trump wrote in a social media post on Monday.

In addition to Section 122 tariffs, Trump said his administration would open Section 301 investigations into unfair trade practices to secure additional levies. Those investigations can take weeks or months.

U.S. Trade Representative Jamieson Greer, during an appearance on ABC’s “This Week” on Sunday, said the administration’s “policy hasn’t changed” despite the Supreme Court setback.

“We found ways to really reconstruct what we’re doing. Now, it doesn’t have the same flexibility that the president had under the previous authority that he was using, but it gives us very durable tools,” Greer said.

Treasury Secretary Scott Bessent, on CNN’s “State of the Union” on Sunday, said other tools will get the administration back to the tariff levels it had before the Supreme Court’s decision.

“We have been in touch with our foreign trading partners, and all of them want to keep the trade deals that have been set,” Bessent said.

Trump on Monday, in another social media post, threatened a “much higher Tariff” if any country decides to “‘play games’ with the ridiculous supreme court decision” that struck down most of his global tariffs — though he didn’t elaborate on how he would impose such levies.

Trump, while criticizing the Supreme Court’s tariff decision, also predicted the justices the could rule against him in other cases, specifically on the 14th Amendment guarantee of birthright citizenship.

The Supreme Court will hear an expedited appeal of Trump’s case seeking to effectively end birthright citizenship by executive order. Federal courts have so far blocked Trump’s order nationwide.

“But this supreme court will find a way to come to the wrong conclusion, one that again will make China, and various other Nations, happy and rich. Let our supreme court keep making decisions that are so bad and deleterious to the future of our Nation — I have a job to do,” Trump wrote in a social media post.

When asked after Friday’s tariff ruling if the justices were still invited to his State of the Union address, Trump said “barely.”

“Honestly, I couldn’t care less if they come,” Trump said.

In that news conference, Trump called the conservative justices who ruled against him an “embarrassment to their families” and the liberal justices a “disgrace to our nation.” Trump’s also heaped praise on the three conservative justices that sided with him on tariffs, on Monday referring to them as “the Great Three!” in a social media post.
