The accidentally publicized list (see Appendix) of private documents held by Trump, that were slurped up by the FBI NARA Warrant, includes a note that there were discussions of pardons for “RN, IR, JC and MB”. The last of these would match Mo Brooks, who is said to have requested a pardon, according to the J6 Committee.
I would expect them to send a subpoena for this document.
EDIT: Looking at the House Freedom Caucus, I also see a Ralph Norman…
EDIT 2: I see an Ignacio Ramos and Jose Compean who were given pardons, together.
