Since then, things have just gotten worse. A couple of days ago, Kevin McCarthy (House Minority Leader) came out public against the committee. Yesterday, Mitch McConnell (Senate Minority Leader) did the same.
This is bad, because it's McCarthy and McConnell that are supposed to choose the five Republican members of the committee. Even if the committee is approved and establish by Congress, it is likely that McCarthy and McConnell will choose the more radical members of their party to sit on it (people like Louie Gohmert, Jim Jordan, David Clyde, Ron Johnson, or Rand Paul).
That would mean no subpoena could be issued to a Republican - especially those who were involved with the rioters. And without the ability to subpoena those involved, the committee would not be able to function properly.
This was a good idea, because there needs to be a thorough investigation of the January 6th riot, but it now looks like an idea that is doomed to failure!
