WASHINGTON, Oct 23 (Reuters) - The Republican chairman

of the U.S. House of Representatives Committee on China demanded

answers on Wednesday from the Commerce Department and TSMC after

a chip made by the Taiwanese company was found in a device made

by China's Huawei.

"Reports that cutting-edge TSMC-manufactured chips have

contributed to Huawei's AI development represent a catastrophic

failure of U.S. export control policy," Representative John

Moolenaar said in a statement. "Congress needs immediate answers

from both (Commerce) and TSMC about the scope and volume of this

disaster."
