Because the tariffs are paid by U.S. companies - not by China as the President has repeatedly insisted - it's presented Republican lawmakers and conservative watchdog groups with a policy quandry.
"Tariffs are a tax on the American people," said ex-Rep. David McIntosh (R-IN) on NBC's Meet the Press, who now runs the group Club For Growth.
Even President Trump has referred in recent days to his tariffs on China as "taxes."
While there is certainly evidence bubbling up among farmers and some Republicans opposed to the tariffs, other GOP officials say the President is right to press this fight against Beijing.
"Do I like tariffs as a policy on any given day? No," said Sen. Marco Rubio (R-FL).
"Either we do something now, or our economy is going to be gutted," Rubio said, arguing the U.S-China trade relationship must be rebalanced, a case that President Trump has made repeatedly.
