Former Nvidia chief executive Jensen Huang has agreed to testify before Congress, House Foreign Affairs Chairman Brian Mast told reporters at the US Capitol on Thursday, Bloomberg reported at 16:13 UTC on 12 November. Huang agreed on Wednesday night after several top lawmakers threatened a subpoena, Mast said, according to Bloomberg.
Bloomberg TV’s chief political correspondent Annmarie Hordern wrote on X that Mast said Huang “has agreed to testify before Congress before Thanksgiving”. Thanksgiving falls on Thursday, 26 November, so the window Mast described closes within 14 days of today, by our count; Thanksgiving is 9 days after Nvidia’s 17 November results.
Business Pill · Concentration Explained
An evergreen Business Engineer explainer on concentration, where a few holdings account for most of the value. It teaches the general idea only and does not discuss Nvidia or its leadership.
The key insight: As we read the reports next to the 4 November letter, the question has moved from whether Huang appears to where and how: the chairs asked for a closed-door briefing on 18 November, and Mast described testimony before Thanksgiving, 14 days from today by our count.
Bloomberg attributes the news to “a key Republican” and names Mast as the source. Mast chairs the House Committee on Foreign Affairs, one of the three committees whose chairs asked Huang to appear on 4 November.
The part of the Bloomberg report we could read does not name the committee or committees, the date, or the format of the session, public or closed-door. Hordern’s post gives the timing as before Thanksgiving and no specific day.
Days from 12 November 2026 to each dated step: Nvidia results (8-K release), the requested House briefing (4 Nov letter), Thanksgiving (testimony before Thanksgiving per Mast, as reported by Bloomberg TV), and the end of the 119th Congress (Twentieth Amendment). Day counts are our arithmetic.
What the House Chairs Asked For
Mast, Select Committee on China Chairman John Moolenaar and Intelligence Committee Chairman Rick Crawford asked Huang to appear for “a joint, closed-door briefing”, according to the Foreign Affairs Committee’s release of 5 November. The topics include “NVIDIA’s security protocols against foreign adversary espionage”.
The 4 November letter reads: “We formally request that you appear in room 2172 of the Rayburn House Office Building on November 18, 2026, to brief our committees.” It asked for acceptance or an alternative date by 11 November, as set out in our piece on the dates ahead.
Moolenaar told Fox Business that if there was no agreement, “I believe there will likely be subpoenas for him to appear”, Reuters reported. Our piece on the subpoena threat covers the deadline and the committee rules Reuters described.
How Many Days Are Left, by Our Count
By our count, the agreement Mast described came 7 days after the chairs’ 4 November letter. From today, Nvidia’s third-quarter results on 17 November are 5 days away, the requested 18 November briefing date is 6 days away and Thanksgiving is 14 days away.
The 119th Congress ends at noon on 3 January 2027 under the Twentieth Amendment, 52 days from today. Thanksgiving falls 38 days before that date, by our count.
Who Would Be Testifying
Nvidia’s board accepted Jen-Hsun Huang’s resignation as president, chief executive officer and a director on 11 November, according to the 8-K, and named finance chief Colette M. Kress interim chief executive. Mast’s account, as reported, places the agreement on the same night. Our report on the resignation covers the filing.
Reuters reported earlier, citing a person familiar with the discussions, that the three House Republicans were unlikely to allow Nvidia’s general counsel to answer the questions in the chief executive’s place. On the Senate side, our piece on the senators’ records letter covers a separate 17 November deadline set for the administration.
The Structural Read
As we read the 8-K, the person who agreed is no longer an Nvidia officer or director, so any testimony comes from the former chief executive while Kress runs the company on an interim basis.
As we read the dates, the 17 November results, 5 days from today by our count, fall inside the window Mast described, which closes on Thanksgiving, 26 November.

“I believe there will likely be subpoenas for him to appear.”
Three Implications
FOR INVESTORS Nvidia reports third-quarter results on 17 November, as set out in the release filed with the 8-K; the testimony window Mast described closes after that.
FOR THE COMMITTEES The chairs’ letter asked for a joint, closed-door briefing; the committees’ press-release pages listed no new Nvidia item when we checked at about 16:20 UTC. Other congressional moves on Nvidia this week are in our piece on the Speaker and the chip bills.
FOR NVIDIA The 8-K names Kress interim chief executive; Reuters reported the House Republicans were unlikely to accept the general counsel in the chief executive’s place.
The framework says: “Three competitive categories within one layer: generalist substrate (NVIDIA), hyperscaler custom (TPU, Trainium, MTIA), merchant custom challengers (Cerebras, Groq, SambaNova).”
As we read it, the framework places Nvidia by its products and customers in the compute layer; the chairs’ letter asks about the company’s security protocols in that layer. The framework does not discuss Congress, testimony or leadership.
Days after the 4 November letter from Chairs Mast, Moolenaar and Crawford. The agreement date is Mast’s account as reported by Bloomberg. Day counts are our arithmetic.
What Is Not Established
When we checked at about 16:20 UTC, the press-release pages of the Foreign Affairs Committee and the China Select Committee listed no new Nvidia item; the newest was the briefing request. We found no statement from Nvidia or from Huang’s representatives confirming the agreement, and we have not read Mast’s remarks in full.
It is not established whether the session replaces the requested 18 November closed-door briefing, whether it is public, or whether testimony is under oath. A request to testify and testimony itself are not findings: no committee has published findings on the matters in the letter. Nvidia was not contacted for this piece.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Mast told reporters that Jensen Huang agreed on Wednesday night to testify before Congress, after subpoena threats, Bloomberg reported, and Bloomberg TV’s Hordern reported the timing as before Thanksgiving, 14 days from today by our count. The committee, the format and the date were not on the Foreign Affairs and China Select Committee press-release pages when we checked at about 16:20 UTC.
A note on sourcing. We read the readable part of Bloomberg’s report, the X post by Bloomberg TV’s chief political correspondent, and the press-release pages of the House Foreign Affairs Committee and the House Select Committee on the CCP (checked at about 16:20 UTC on 12 November). The 4 November letter and the Reuters reports are quoted from our earlier pieces. Day counts are our arithmetic. Nvidia was not contacted for this piece.
