House Minority Leader Hakeem Jeffries said Monday that he will push to include tighter restrictions on advanced chip exports to China in the annual defense policy bill, adding House support to a bipartisan Senate effort.

Jeffries told reporters he strongly supports provisions in the Senate version of the National Defense Authorization Act, or NDAA, that would restrict China’s access to chips. He said lawmakers would “work hard to make sure that those provisions make it into the final version” of the bill.

The Democratic leader’s comments came a day after Nvidia’s board announced an independent investigation into CEO Jensen Huang’s affair with a woman suspected of being a Chinese spy. The development has intensified attention on the national security implications of exporting advanced artificial intelligence technology to China.

Jeffries’ support strengthens the Senate push in the House as Democrats prepare to take control of both chambers of Congress following their strong midterm showing.

The Senate legislation, known as the AI Overwatch Act, would allow Congress to review licenses for sales of advanced AI chips to China and other countries of concern. Other provisions would help track where exported chips ultimately go and tighten restrictions on sales of the equipment used to manufacture them.

Sens. Elizabeth Warren, a Massachusetts Democrat, and Jim Banks, an Indiana Republican, also called Monday for the AI Overwatch Act to be included in the defense bill. They cited reports that Nvidia had secured approval to export hundreds of thousands of advanced AI chips to China, including to companies tied to the Chinese military.

In a joint statement, the senators said Huang’s confirmation of a relationship with a suspected Chinese intelligence operative made national security concerns more urgent. They also said it raised questions Nvidia must answer about whether the reported activities were connected to the company’s chip exports.
