That isn't going to happen anytime soon... the US government is slow to act on anything, and it will take more people than the one lawmaker if they are to remove Gary Gensler to public pressure.
I see that there is great interest/desire in the crypto community to see Gary Gensler removed from his position. The political process is often complicated and public sentiment can play a role as well. I think, even though the majority with many votes wins, all decisions are at the fingertips of the legislators and the procedures set out in the political system.
