Some key figures from Jan. 6 were suspiciously absent from latest round of subpoenas

The House select committee investigating the Jan. 6 insurrection issued another round of subpoenas this week, but the names of some key figures were missing.

The committee issued its fourth batch of subpoenas seeking information related to the U.S. Capitol riot, this time targeting organizers of a "Stop the Steal" rally outside the White House that drew thousands of supporters to hear a speech from then-president Donald Trump, although some of the leading organizers still haven't been ordered to turn over documents, reported the Washington Post.

"The subpoenas issued by the select committee Wednesday focus on the individuals identified as rally organizers in the permit for the rally at the Ellipse, including [Women for Trump leader Kylie] Kremer and her mother, Amy Kremer," wrote the Post's Philip Bump. "They do not, however, include those who sought permits from the Capitol Police for rallies there."

"This is a noticeable gap," Bump added. "It's not just that the rally at the Capitol was an early indicator of what was to come or that it was obviously located right at the place where violence broke out on the day of the riot, it's also that the rally was obviously a function of the fringier elements of Trump's coalition and included close Trump allies."

Trump himself promoted the event, which he promised Dec. 19 would "be wild," and the website WildProtest.com, likely a project of right-wing provocateur Ali Alexander, invited Trump supporters to protest at the Capitol, and at some point his rally and the one at the Ellipse were blended together into one package called March to Save America.

Organizers were concerned by the overlap between the fringier rally at the Capitol and the one at the Ellipse, and the latest batch of subpoenas includes Cindy Chafian, who submitted permits on behalf of Women for Trump, and Trump aide Katrina Piersen, who had assured the president that Alexander's rally would focus on him and his speech.

The committee has asked the National Archives to provide copies of any communication between the White House and Alexander, conspiracy theorist Alex Jones and longtime Trump associate Roger Stone -- who all were scheduled to speak at the Capitol rally -- but so far no subpoenas have targeted the organizers of that event.

"That certainly doesn't mean that none will come; the committee's work is still in its early stages," Bump wrote. "But it stands out as an existing gap. There was a rally planned for the Capitol grounds organized by far-right allies of the president's and at which a close ally of Trump's, Stone, was scheduled to speak."

"It's an area on which the committee will necessarily need to shed light but, as of now, remains stubbornly in the dark," Bump added.
