Why it matters: Secret Service disclosures have been a major focus of the committee since testimony at its public hearings in June and July revealed the agency’s role in major events on Jan. 6. News lead: Speaker Bennie Thompson (D-Miss.) told reporters that the materials obtained are “a combination of a number of text messages, radio traffic … thousands of exhibits.”

Thompson said the material consisted “mostly” of texts from agents on Jan. 5 and Jan. 6, but declined to elaborate because the committee is still reviewing them. “The doses we received were significant,” he said. “It’s a work in progress.” Rep. Zoe Lofgren (D-Calif.), another member of the committee, told MSNBC on Wednesday “it’s a large amount of information that we really pushed hard for the agency to release.”

The context: The panel also began contacting the Secret Service this summer about deleting agents’ texts from Jan. 5 and 6 in what an agency spokesman said was a “premeditated, three-month system migration.”

This resulted in a subpoena seeking “the relevant text messages, as well as any subsequent reports issued to any and all departments of the USSS relating or relating in any way to the events of January 6, 2021.”

The background: The Secret Service came under the committee’s spotlight during its hearings over the summer, in which former Trump administration aides testified that agents were central to key events on Jan. 6. What we’re watching: Lofgren noted that the materials the committee has received so far are not exhaustive.

“There’s texting, there’s email, there’s radio traffic, there’s all kinds of information. [Microsoft] Group meetings,” said MSNBC anchor Nicolle Wallace. “We go through everything that has been provided. More to come.”

The flip side: Secret Service spokesman Anthony Guglielmi told Axios that they “continue to cooperate fully with the January 6th Select Committee,” but “no additional text messages were recovered.”

Instead, he said, the agency provided the panel with “a significant level of detail from emails, radio broadcasts, Microsoft Teams chat messages and reports concerning aspects of planning, operations and communications around January 6.”
