Sen. Tillis threatens to block Senate crypto bill over missing ethics rules.

Senator Thom Tillis has put the Senate's crypto bill on notice, warning he will vote against it unless the legislation includes explicit ethics language restricting how government officials can hold or use digital assets. The statement introduces a meaningful procedural obstacle at a moment when the bill's supporters had been cautiously optimistic about floor progress.

Tillis's demand reflects a broader tension in Washington: as crypto assets become more valuable, the question of whether lawmakers and executive-branch officials should be allowed to hold them — or profit from related policy decisions — has moved from a fringe concern to a mainstream legislative sticking point. Whether sponsors can negotiate ethics provisions without losing other votes remains the key variable.
