Fake news
Unnamed GOP leaders
The only source provided is a quote from John Thune who says some members are “very concerned” and that if this continues ““Congress is going to want to probably be heard from” ... which could mean anything, but WaPo spins it to mean - in terms of trying to limit Trump’s tariff authoriy - without providing any additional quote or source to support that interpretation.
Agreed, they can't possibly be that stupid.
Thune may hear from a primary challenger if he is not careful.
