The congressman leading the charge on this are Republicans. It definitely varies when it comes to each individual politician, but from what I see it does seem that the Republican party is generally more crypto-friendly.

To provide some context, currently President Biden (Dem) is trying to clamp down on crypto and any supposed "loopholes", while another Democrat named Elizabeth Warren is basically on the warpath against crypto and is one of Gary Gensler's biggest supporters.

I personally think the Democrats attacking crypto is going to lose them support from the American youth and crypto enthusiasts. Which could help crypto- if crypto-friendly politicians take their place in the next election.
