He is a Trump hater and a card carrying member of the Swamp, who holds the concept of upheaval of that Swamp as something horrible.
Which is why McCarthy put him there.
I think you need to reevaluate your judgement of Massie.
He certainly had issues with things Trump did. So did I.
The CARES act was one of the worst pieces of legislation in US history. It is one of the main causes of our inflation and terrible economy.
He was also critical of Trump pushing and praising the failed vaccines.
As far as I know, Massie never believed the Russia hoax or supported either of the impeachments or even criticized Trump for any personality issues.
Like Rand Paul, he is a libertarian purist and didn’t like when Trump did anti-libertarian things. That doesn’t make him a “Trump hater” and certainly not a member of the swamp.
I predict he will make the right decision here if he truly does have the power to affect it.
