They’re in the same party, but Wisconsin Republicans like House Speaker Paul Ryan, U-S Senator Ron Johnson and Governor Scott Walker are speaking out against the president’s plan to add tariffs to steel and aluminum imports.  The high-profile politicians say the move could start a trade war and hurt Wisconsin agricultural and manufacturing industries.  Democratic U-S Senator Tammy Baldwin is asking President Trump to exempt European trading partners while doing more to target cheating by China.  Trump has already excluded Canada and Mexico from the tariffs, but he’s moving ahead with his plan.  Senator Johnson says he’s not sure there are ever any winners in a trade war.
