Export controls need to be tightened after revelations the Chinese company used Nvidia technology, the leaders of a congressional committee said.

Two U.S. Congress members are calling on President Donald Trump's administration to consider restricting the export of artificial intelligence chips made by Nvidia, alleging Chinese AI firm DeepSeek has relied on them.

Trump administration officials are exploring additional curbs on the sale of Nvidia Corp. chips to China, according to people familiar with the matter, who emphasized that conversations are in very early stages as the new team works through policy priorities.
