The House Ways and Means Committee will mark up a Democratic resolution Wednesday demanding that the White House turn over all internal documents pertaining to its decision to levy 25 percent tariffs on steel imports and 10 percent ones on aluminum ones. The request is meant to help understand what was going on behind the scenes at the White House as President Trump prepared to take on China on trade.

The binding resolution, introduced by Rep. Bill Pascrell, D-N.J., calls for “any and all documents in draft or final form, including reports, memos, spreadsheets, and slide deck presentations” relating to the process for the creating the tariffs. It also demands documents relating to “any actions the Administration has considered taking to offset harm to United States exporters facing tariffs that have been or will be imposed by other countries in response to United States tariffs.”
