Trump will explain tariffs on electronics on Monday

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.

The White House is putting together a relief plan to support out American farmers "if necessary," Agriculture Secretary Brooke Rollins said in an interview Wednesday

"The President has our farmers' and our ranchers' backs, just as in the first term. We are already putting together — if necessary, we're hopeful not necessary, but if necessary — a package that can mitigate a lot of that damage, if not all of it," Rollins told News Nation without any further details.

"But that is a long-term question. We really won't know the full impact for months to come," she added.
