According to a letter obtained by NBC News, the U.S. Secret Service handed over a single text message thread in response to a subpoena.

That development was revealed by the Secret Service in a letter sent Tuesday, the deadline for the agency to hand over a trove of documents related to the insurrection.

CNBC requested comment from the Secret Service and the select committee.

The select committee was told that the Secret Service texts had been erased due to a device-replacement program. The inspector general for the Department of Homeland Security briefed the select panel about the missing text messages hours before the subpoena was issued.

The inspector general told congressional committees that the messages had been deleted after his office asked the Secret Service for records related to the Capitol riot.

Anthony Guglielmi, a spokesman for the Secret Service, said last week that the agency has cooperated with the OIG. Some data was lost when the Secret Service reset its devices in January 2021.

The inspector general of the Department of Homeland Security requested text messages from 24 Secret Service personnel during the period of December 7, 2020 through January 8, 2021.

After receiving that request, the letter said that the Secret Service identified a text message conversation from former U.S Capitol Police Chief Steven Sund to former Secret Service Uniformed Division Chief Thomas Sullivan requesting assistance on January 6, 2021.

The select committee received one text message from the Secret Service, according to one of the members. Lofgren said that the message may have been captured by another branch of government.

The Secret Service turned over 10,569 pages of documents by Tuesday's deadline.

The Secret Service continues to engage in extensive efforts to further assess whether any relevant text messages sent or received by 24 individuals were lost due to the Intune migration.

The National Archives and Records Administration asked the Secret Service to look into the deletion of texts.

The uproar over the text messages comes at a time when the public is more interested in the Secret Service than ever before.

According to Cassidy Hutchinson, a former White House aide, Trump lunged at a Secret Service agent after being told that they wouldn't drive him to the Capitol.

News outlets reported that Secret Service sources disagreed with her comments. The agents with knowledge of the incident have yet to challenge Hutchinson's claims.

There will be a public hearing at 8 pm. The time is Thursday.
