Nvidia is the most valuable firm on earth. It is also at the center of a fight in Washington over China.
Its CEO just bowed out of that fight. Jensen Huang turned down a Senate invite to testify.
The invite came from Senator Elizabeth Warren, a Democrat from Massachusetts. She wanted Nvidia to answer on its sales in China.
She also asked about U.S. rules on selling top chips abroad. Huang said he was "unable to attend."
He did not go quiet, though. He sent a letter back.
In it, he said Nvidia built the first big AI computer for U.S. labs over a decade ago. He added that he believes in "the American system."
The hearing carries a bold title. It is called "AI and the American Dream."

Nvidia makes the chips behind most of the world's AI. That makes it the prize in this debate.
Washington is split on those chips. Some want them sold freely, others want them kept from China.
China has long been a big market for Nvidia. Tighter export controls there could squeeze a real slice of sales.
The fight comes down to one question. Who should get the world's best AI chips?
For Nvidia, the answer shapes a huge slice of future sales. The stakes could hardly be higher.
Warren was not satisfied with the no. "The American people deserve answers in a public forum," she shot back.
This is not the first clash between the two. Late last year, Huang said U.S. firms should offer their best chips to China too.
Warren pushed back then as well, warning that such sales could help China's military. The two have not seen eye to eye since.
Huang is no stranger to Washington. He has pressed officials for months to let U.S. firms sell more abroad.
Huang has a seat on a White House science panel. He also flew with President Trump to meet Xi Jinping in May.
Warren took aim at that trip. If he can dine at Mar-a-Lago and fly to meet Xi, she said, he can find time for Congress.
Huang did make an offer. He asked Warren and others to visit Nvidia's office instead.
The AI hearing goes on Thursday with or without him. Warren's team is still hunting for another date to get him on the record.
For now, the seat saved for Huang stays empty. The China questions are not going away.
For investors, one worry stands out. It is how hard Washington leans on the China sales that keep Nvidia on top.
Nvidia's toughest rival right now may not be another chipmaker. It is Washington.
