Watch: Trump trade representative Jamieson Greer, Rep. Steven Horsford have fiery exchange on tariff pause

As President Trump announced a pause to his sweeping reciprocal tariffs Wednesday, his trade representative, Jamieson Greer, was in the middle of testifying at a House hearing on the administration's trade policy. 

Greer appeared to learn of the president's decision to pause the tariffs for 90 days the same time the public did, as he was sitting before members of the House Ways and Means Subcommittee on Trade. 

Asked when he was made aware of the pause by Rep. Steven Horsford, a Democrat from Nevada, Greer said, "Well, I understood the decision was made a few minutes ago. It's something that's been under discussion."
