"A billionaire backer of Donald Trump has urged the US president to pause his recently announced trade tariffs, or risk "a self-induced, economic nuclear winter".
Amid market turmoil, hedge fund manager Bill Ackman said the president should take three months to allow countries to renegotiate their trading relationships with the US."
"In his post on X, external on Sunday, Mr Ackman acknowledged the Trump argument that the global trade system had "disadvantaged" the US.
But, he wrote, tariffs that Trump had imposed were "massive and disproportionate", and did not distinguish between American friends and enemies."
