The author claims that Nancy Pelosi’s J6 committee is unconstitutional in two ways. First, because it’s composition violates the rules that govern the formation of the committee. Second, because the committee has issued “general search warrants” that the Constitution expressly forbids (4th Amendment).
The claims seem legitimate to me and I hope the reported lawsuits prove successful. You’d think, however, that Congress would avoid unconstitutional behavior as a matter of course.
