I do not think some of the arguments they use will sway Trump very much. For instance
... they said the President's decision to lift import tariffs to 25% will disproportionately impact the working class
Trump has only contempt for those who are not rich, and will assume the working class is too ignorant to know the reason for the increased prices. Besides, many are Democrats.
He may be slightly more worried by
... higher levies threaten the future of some businesses.
but only if unemployment goes in the wrong direction which does not seem imminent.
Backing down on the trade war with China would make Trump look weak. He is not going to risk that just for the long term health of the US economy.
