But that's "in principle." Will they? Almost certainly not. (Though it's unclear why this is the case.)
That does mean a fair number of Republican Congresspeople would have to join Democrats. This level of cooperation seems to be in itself anathema to Republicans, notwithstanding the actual principle of the bill itself.
Historically congress has given the executive branch added decision making over tariffs, but congress can revoke those and/or curtail tariffs if they wish.
But congress is GOP controlled and they're barely a political party as far as independent thinking goes and more so a Trump fan club in all but name.
