President Donald Trump was apparently up late on Monday evening, posting a series of middle-of-the-night messages on his Truth Social platform focused on his signature trade policy.

“The biggest threat in history to United States National Security would be a negative decision on Tariffs by the U.S. Supreme Court,” Trump wrote on Truth Social at 2:37 a.m. Tuesday. “We would be financially defenseless.”

The pending decision is clearly looming heavy on Trump’s mind. The Supreme Court will soon rule on whether Trump has the authority to impose sweeping tariffs by invoking the International Emergency Economic Powers Act — without congressional approval. Justices appeared skeptical of Trump’s power to do so during arguments, perhaps explaining the president’s anxiety about the upcoming ruling.

In a follow-up post on Truth Social, Trump claimed the import taxes have only benefited the U.S.

“Because of Tariffs, easily and quickly applied, our National Security has been greatly enhanced, and we have become the financially strongest Country, by far, anywhere in the World. Only dark and sinister forces would want to see that end!!!” he wrote at 2:45 a.m.

Meanwhile, on Monday, Trump announced a major aid package to help farmers who have struggled under his trade war. Trump claimed making the payments “would not be possible” without the revenue brought in by his tariffs, even though his trade war has exacerbated the farmers’ financial troubles and has made distributing the aid necessary.

“Affordability is a real issue,” Rep. Marjorie Taylor Greene (R-Ga.), a onetime Trump ally who has since fallen out with the president, told CBS’s “60 Minutes.” “It’s one of the top issues. Not only in my district. It’s across the country.”
