Republican Sen. Ron Johnson of Wisconsin says that the Trump administration's $12 billion bailout for American farmers hurt by tariffs would be a "mess" to implement, saying it's his responsibility to convey to constituents "the harm" caused by ongoing trade disputes. But Johnson said he's "encouraged" by the president's latest round of talks with the European Union, which he said shows Trump is "moving forward."

"President Trump is trying to shock the world trading system because ever since World War II America has been very generous. Our trading partners have taken advantage of our generosity," Johnson said on Sunday. He said he welcomed a commitment by the U.S. and EU to halt imposing new tariffs while negotiating a new trade deal.

Johnson's criticism of the president's trade policy was much softer in tone than it was earlier in the week. In a letter to the White House, Johnson wrote that permanent damage had already been done and a $12 billion aid package to farmers was reminiscent of a "Soviet-era economy."

Pressed on Sunday whether he supports the president's bailout package for farmers, Johnson replied: "No, no, no, no.  Hopefully it never gets implemented."
