Republican Senator Joni Ernst says a “brush fire of retaliation” could erupt if President Trump doesn’t reconsider imposing tariffs on steel and aluminum imports — and Iowa’s economy will suffer.

Ernst cited notable Iowa manufacturers like John Deere, Vermeer, Lennox and Des Moines Steel as companies that would be hit with higher production costs.

Ernst says she agreed with President Trump “on many things,” but she warns tariffs will prompt customers in other countries to buy elsewhere.
