Tariffs need Congressional approval, right? Any chance they don’t pass?

I’m reacting to tariffs like the new one slapped on Asian autos wondering if we should buy now knowing it will be $12K more costly later.

But knowing Congress has the power of the purse, could the GOP senate or house choose to “represent constituents including big Auto” and possibly defy Trump? I get it they are spineless and some are MAGhats, but aren’t they giving up their future power potentially giving into voting FOR tariffs?

This is different from defying Elon who will spend to out primary you.

And also how likely is the threat to their physical selves with what we see now from this administration?

Such a weak Congress is a travesty. But free trade is the best selfish outcome and better for power hungry congressional leaders, right? Or defying Trump’s poor economic decision is more costly to them?
