The evidence strongly supports the truthfulness of the statement. The most authoritative source is the official media page for the U.S. House Select Committee on the CCP, a primary source with very high authority and relevance. It directly confirms that the committee sent a letter to the Secretary of Commerce regarding the sale of Nvidia H200 chips to China. A formal letter of this nature is a direct request for information and is functionally equivalent to requesting a briefing. This is strongly corroborated by multiple other relevant sources. One news article directly reports that lawmakers from the committee requested government documentation on the sale of H200 chips, while another quotes the committee chair expressing public concern over this specific issue. While some sources provided are irrelevant or have low authority, there is no conflicting evidence. The core claim is consistently supported by the most credible sources available.
