Jordan's got the longest-running paper trail with the committee to date.
The select committee got things rolling on December 22, 2021 by asking Jordan to testify about his communications with Trump before, during, and after January 6, 2021 regarding challenging the election results.
In his initial response on January 9, 2022, Jordan said he had "no relevant information" to offer the committee, and took investigators to task for even asking.
"This request is far outside the bounds of any legitimate inquiry, violates core Constitutional principles, and would serve to further erode legislative norms," Jordan wrote in his first letter back to the committee.
After he'd been subpoenaed, Jordan noted that he was still waiting to hear back about questions he posed to the committee in January and bristled at the "dangerous escalation" of compelling him to testify.
"You have not substantively addressed any of the points in the letter or alleviated any of the concerns I raised," Jordan wrote on May 25 adding, that the same concerns "still exist today and have only grown as the Select Committee has continued to leak nonpublic information in a misleading manner in the intervening period."
A federal judge, however, dismissed Republican contentions that the committee is improperly constituted and doesn't serve a legislative purpose, and recently a judge swept aside similar arguments made by one-time Trump advisor Steve Bannon in his failed attempt to get his contempt of Congress trial dismissed.
Jordan delved even deeper into why he's unlikely to ever testify before the committee in the 11-page, heavily-footnoted letter he sent the panel on June 9. In that third missive, Jordan contests the panel's formation, membership, subpoena powers, and "legislative purpose," among other things.
"You seem to believe that you have the authority to arbitrate the scope of a colleague's official activities," Jordan wrote on June 9. "Respectfully, I do not answer to you or the other members of the Select Committee. I am accountable to the voters of Ohio's Fourth Congressional District."
