A paragraph in Jennifer Rubin's column today caught my eye. (Link in said para).

Several of the signatories are represented by Mark Zaid, who provided me with a copy of a letter challenging the fishing expedition. In a response to the chairmen, Zaid notes that the power of Congress to exercise oversight is not “unbounded.” Citing the 2020 Trump v. Mazars Supreme Court case, Zaid explains that Congress needs a legitimate legislative purpose to demand compliance with a subpoena. And here, “no conceivable legislative purpose” exists, he says, only a “purely political, partisan exercise” that wastes taxpayer money. [snip]

However, should the committees issue formal subpoenas to others or demand the former officials reveal classified information about their past service (which is the basis for their opinions set out in the statement), the issue likely would head to the courts in the first substantial legal challenge to the House GOP’s conspiracy-driven inquests.

The last thing these right-wing congressmen likely would want is a court ruling that their three-ring circus lacks any legitimate legislative purpose and, therefore, cannot compel testimony or document production. A legal defeat for MAGA-inspired investigations (which to date have spectacularly flopped) would be the perfect denouement to Republicans’ inept efforts to harness congressional power for political gain.
