Kevin McCarthy made the decision not to allow Republicans to serve on the committee after Speaker Nancy Pelosi rejected two of the five Repubicans selected, Reps. Jim Jordan and Jim Banks. Pelosi rejected them on solid grounds. Jordan could possibly have been subpoenaed to testify. Both were trump allies who were supporters of decertifying the election results. A "senior Republican" said at the time that Pelosi's move was a "gift" to Republicans because they never wanted to take part in the hearing and, if they were on the committee, would be forced to confront complicated questions over trump's role in January 6. McCarthy made it clear, he wanted members who would protect trump. If he couldn't get that his Plan B was to have NO Republicans on the committee so he could claim it was all a partisan witch hunt.
Republicans Liz Cheney and Adam Kinzinger agreed to serve and thus became pariahs in their own party. Are they outcasts with an axe to grind? I doubt that's the way history will judge them.
I repeat. I've been reading about events in Ukraine since Russia invaded. This type of propaganda and spin seem very familiar. The pro-Russian Ukraine official insisting to a Western journalist that reports of Russian attacks on his city were lies, while ongoing shelling was visible through, and rattling, this official's office windows.
Birds of a feather...
