WASHINGTON—Seeking to reassure the public after his latest tariffs sent both U.S. and international markets into free fall, President Donald Trump calmly reminded the nation Thursday that desire is the root of all suffering.

“My fellow Americans, remember that attachment to worldly things stands at the very foundation of the illusions that lead us to experience deep anguish,” said the commander-in-chief, who reportedly sat in a full lotus position on the Oval Office floor as he noted that to base one’s contentment on access to affordable food, cars, electronics, shoes, clothing, furniture, or various other imports was to make one’s existence as fickle as the stock market itself.
