We have all have seen how Congress treats Eric Holder, James Clapper, and James Comey for Contempt of Congress and lying under oath.
Didn't Fauci get caught red-handed lying to Congress after he was skewered by Senator Rand Paul?

A Contempt of Congress charge would hurt them more if you rolled it up and poked them in the eye with it!
