This 2018 Reuters story on reuters.com says:
The red, white and blue banners for U.S. President Donald Trump’s second-term campaign are ready to ship, emblazoned with the words “Keep America Great!”
But they are made in eastern China and soon could be hit by punitive tariffs of Trump’s own making as he ratchets up a rancorous trade dispute with Beijing.
At the Jiahao Flag Co Ltd in Anhui province, women operate sewing machines to hem the edges of “Trump 2020” flags the size of beach towels, while others fold and bundle them for delivery.
The factory has turned out about 90,000 banners since March, said manager Yao Yuanyuan, an unusually large number for what is normally the low season, and Yao believed the China-U.S. trade war was the reason.
Is it true that the Trump campaign was having campaign banners made in China?
