Trump will explain tariffs on electronics on Monday

Rep. Darin LaHood, an Illinois Republican, expressed concerns about the impact of President Donald Trump's tariffs on farmers and the agriculture industry.

"As I talk to my farmers, there's a lot of anxiety, a lot of stress, a lot of uncertainty because when we get into a trade war, usually the first pawn in the trade war is agriculture," LaHood told U.S. Trade Representative Jamieson Greer. "And as we look at the timeline and chronology moving forward, Ambassador Greer, what would you tell my farmers in terms of that uncertainty and anxiety that they're feeling right now?"

Greer did not answer directly, instead saying not all countries have said they will retaliate against the U.S.

U.S. Trade Representative Jamieson Greer confirmed on Wednesday that he is also serving as the acting head of the Office of the Special Counsel, an independent investigatory agency that is partly tasked with protecting whistleblowers.

Democratic Rep. Linda Sanchez pressed Greer during Wednesday's Ways and Means Committee hearing on whether holding both roles represented a conflict of interest.

"Well, I certainly would recuse myself if there was an issue involving me or my agency," Greer said.

Some Republican members of the House Ways and Means Committee pressed U.S. Trade Representative Jamieson Greer on what is the administration’s game plan with its sweeping tariffs that went into effect.

“Now there's this discussion about be doing some trade deals. What does that mean? What is that process?” Florida Rep. Vern Buchanan asked Greer.

Greer responded that Trump is open to negotiating with countries that want "reciprocal" trade and to reduce deficits. Buchanan followed up by pressing for more details on the process going forward, which Greer didn't directly answer but said some long-term negotiations with other countries “might require, you know, congressional action.”

Greer added that he had meetings on Tuesday with his counterparts from the European Union, South Korea, Ecuador, and Mexico.

President Donald Trump told Republican lawmakers on Tuesday night that pharmaceuticals imports will soon be hit with "major" tariffs. U.S. Trade Representative Jamieson Greer was asked on Wednesday by Rep. Lloyd Doggett, D-Texas, if that was true.

"He said he will impose them, now the extent of that is subject to investigation," Greer said.
